Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50. Write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit, b, Harper can buy.

Answers

Answer:

4.75x + 3.75y ≤ 15 inequality models the given situation.

Harper can buy at maximum 3 bags of fruits.

Step-by-step explanation:

Given : Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50.

We have to write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit that Harper can buy.

Let Harper buys 'x' bags of fruit

and 'y' box of crackers

Given : cost of one bags of fruits is $ 4.75

so the cost of x bags of fruits is 4.75x

Given : cost of one box of cracker is $ 3.50

so the cost of y box of crackers is 3.75y

also, Harper has $15.00 to spend at the grocery store

So the maximum amount he can spend is $15

So inequality become,

4.75x + 3.75y ≤ 15

So the maximum number of bags of fruit Harper can buy.

is when he buys no box of cracker.

Put y = 0 in above inequality , we have,

4.75x + 3.75(0) ≤ 15

4.75x ≤ 15

Divide both side by 4.75

We have , x = 3.158 ≈ 3

So , Harper can buy at maximum 3 bags of fruits.

since harper has only %15 that is the most she can spend, therefore we would have 15> or = 4.75b+3.5c. the best way to solve this would be to divide 15 by 4.75, then round down to the nearest whole number. if you do this, you get 3 bags of fruit.

julian earns $13.50 per hour. His company deducts 23% of his pay each week for taxes. Julian uses the expression 0.77 ( 13.50h) to compute his earnings after taxes for the hours h he works. what will be his earnings after taxes, if he works 40 hour?

Answers

If Julian works 40 hours per week and you would like to know what are his earnings after taxes, you can calculate this using the following steps:

per one hour: 0.77 * (13.50 * 1h) = 0.77 * 13.50 = $10.395
per 40 hours: 0.77 * (13.50 * 40h) = 0.77 * 13.50 * 40 = $415.8

Result: His earnings after taxes will be $415.8.

for this problem, all you have to do is plug 40 into the equation given. when we do this we get .77(13.50*40). this simplifies 415.8, so he earns, after working 40 hours, $415.80

A purse contains $2.45 in dimes andquarters. There are two more than
twice as many dimes as quarters. How
many of each coin are in the purse?

Answers

Answer:

dimes = 12, quarters =5

Step-by-step explanation:

Let x stand for quarters. So if there are two more than twice as many dimes than quarters than it would look something like

d = 2x+2

q = x

Now multiply them by the value of the coin, to get them into cents. So you'd multiply dimes by twn (2x+2*10) which is equal to 20x+20. Multiply quarters by 25. x*25=25x

Now make an equation. 20x+20+25x=245

45x=225

x=5

q = 5

d = 12
