Answer: not proportional

Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)= $(y)/(x)$

$\Rightarrow\ k=(3)/(2)$ =1.5

$\Rightarrow\ k=(7)/(4)$ =1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.

The answer is:Not proportional

The neighborhood ice cream truck driver has to pay $650.00 a week to rent his truck. Each ice cream cone costs $0.75 to make and sells for $1.60. Set up an equation to figure out how many ice cream cones must be sold to make a profit of $100.00 for the week.

Answers

Answer: $0.85x – $650 = $100

Step by step explanation:

Ice cream truck rent $650.00 a week

Each ice cream cone costs $0.75

Sells Ice cream cone for $1.60

How many ice cream cones must be sold to make a profit of $100.00 for the week = x

Capital amount per week = $650 + $0.75 (per cone)

Profit per cone: $1.60 – $0.75 = $0.85

In order to make $100 profit, the expression would be:

$0.85x – $650 = $100

it would be 1.60x-.75x-650=100 i believe bc you would need to subtract the cost of everything that’s due and find what x is to make it equal 100$ profit

Mason spent $15.85 for 3 notebooks and 2 boxes of markers. The boxes of markers cost $3.95 each, and the sales tax was $1.23. Mason also used a coupon for $0.75 off his purchase. If each notebook had the same cost, how much did each notebook cost?

Answers

Let X be the cost of 1 notebook and Y be the cost of 1 box of markers.

The presented information gives us the equations:
3X + 2Y = $14.62 (14.62 is the total cost of 15.85 minus the sales tax of 1.23)
Y = 3.95

Plug the value of Y in the second equation into the first equation to get:
3X + 2(3.95) = 14.62

Simplify and solve for X:
3X + 7.9 = 14.62
3X = 6.72
X = 2.24

The cost of each notebook is $2.24

Solving for the cost of each notebook?
Step 1: You need a variable to represent the notebooks so let used z. It doesn't matter the letter could be x , y , z.
We have 3 notebooks so, 3z (notebooks) will be used when we set up the equation.

We see 2 boxes of markers @ $3.95 each, so 2( 3.95) is our markers.

Problem: 3z + 2(3.95) = $15.85 amount spent w/ taxes

Step 2: Subtract taxes and discount coupon from total amount spend.
15.85 - 1.23 (w/taxes) = $14.62
14.62 - .75 (coupon used) = $13.87

New equation: (without coupons and taxes)

Multiple 2 x 3.95 markers    3z + 2(3.95)= 13.87
  3z+7.90 = 13.87
Subtract:(7.90) form both sides       -7.90 -7.90
  3z =   5.97
Divide 3 from both sides 3 3
z is cost of each notebook   z = $1.99 (cost each notebook)

Check:Multiply 3(1.99) + 2(3.95) + .75(coupon) + 1.23 taxes= $15.85
Add amounts 5.97 + 7.90 + .75 + 1.23 = $15.85
13.87 + .75 + 1.23 = $15.85
14.62 + 1.23 = $15.85
Correct solution both are equal: $15.85 = $15.85
