a baker is calculating the charge for two types of cookies. what formula tells the cost, in dollars, if chocolate chip cookies are $2.00/dozen and lemon frosteds are $1.50/dozen? let c=number of dozens of chocolate chip cookies; l=number of dozens of lemon frosteds; t =total charge. A. T=3.50(L+c) B. T=200c+150L C. T=2.00c+1.50L D. T=1.50c+2.00L

Answers

If you would like to find the formula that tells the cost in dollars, you can calculate this using the following steps:

c ... number of dozens of chocolate chip cookies
l ... number of dozens of lemon frosteds
t ... total charge
t = c * $2.00 + l * $1.50
t = 2.00 * c + 1.50 * l

The correct result would be C. T=2.00c+1.50L.

Answer:

Option C is correct

T= 2.00c+1.50l

Step-by-step explanation:

Given the statement:  

A baker is calculating the charge for two types of cookies.

Here,

c =the number of dozens of chocolate chip cookies,

l=number of dozens of lemon frosteds and  

T =total charge in dollars.

If chocolate chip cookies are $2.00/dozen

then;

Cost of chocolate chip cookies in c dozen = $ 2c

It is also given that:

lemon frosted are $1.50/dozen

then;

Cost of lemon frosted in l dozen = $ 1.50 l

Then total charge(T) in dollars for this problem is given by:

T= 2.00c+1.50l

Therefore, the formula tells the cost, in dollars is,

T= 2.00c+1.50l

Use the following figure to answer the question.When line t is perpendicular to both line l and line m, then lines l and m are parallel.

Which of the following are steps in the process in solving application problems using the two-order system? Assign two variables for the unknowns.

Make a guess for the value of the variables.

Write two equations using the assigned variables.

Make another guess, based on the results of the first guess. Solve the pair of equations.

Answers

Answer:

Options A, C and E are correct.

Step-by-step explanation:

a. Assign two variables for the unknowns.- Firstly we read the problem and then assign values like (x and y) to the unknown entities.

c. Write two equations using the assigned variables. - After the first step, we get few equations to be solved. These equations are based on the assigned values from step 1.

e. Solve the pair of equations. - Finally we solve these equations to get the variable values.

Answer:


Step-by-step explanation:

Assign two variables for the unknowns.

Write two equations using the assigned variables.

Solve the pair of equations.

A company makes a product and has no way to determine which ones are faulty until an unhappy customer returns it. Three percent of the products are faulty and will cost the company $200 each in customer service and repairs. If the company does not refund the customer when repairing the item, how much should the company charge to make a profit of $2.00 per item? $6.00 $6.19 $8.00 $8.25

Answers

(x) - (0.03)(200) = 2.00 
Let x be the company charge to make the profit 

solving for x gives 8$

Answer: $8.00


Step-by-step explanation:

Given: Percent of products which are faulty=3%=0.03

Cost of each faulty product =$200

Let x be the company charge to make the profit .

According to the question,



x-0.03*200=2.00\n\Rightarrow\ x-6.00=2.00\n\Rightarrow\ x=2.00+6.00\n\Rightarrow\ x=$8.00


Hence, the company should charge $ 8.00 to make a profit of $2.00 per item.

Sixty percent of Company A’s employees are considered top performers. Fifty five percent of Company A’s employees are in a rigorous training program. Assuming these two statements are true are most of Company A’s employees in the rigorous training program considered top performers?

Answers

Answer:33 %

Step-by-step explanation:

Given

60 % of company A's employees are considered  top performer

55 % of company A's employee are in a rigorous training program.

Now Company A's employees in the rigorous training program considered top performer are 0.60* 0.55=0.33

That is 33 % of employee is in rigorous training and top performers.
not exactly. there are still 40 percent of the employees that are not top performers. for all you know those 40 percent could make up the majority of the employees in the training program
