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
Anestetic [448]

Answer:

Step-by-step explanation:

Let x represent the maximum number of bags of fruit that Harper can buy.

She is going to buy bags of fruit that cost $4.75 each and one box of crackers that cost $3.50. This means that the total cost of x bags of fruit and one box of crackers would be

4.75x + 3.5

If Harper has $15.00 to spend at the grocery store, it means that

4.75x + 3.5 = 15

4.75x = 15 - 3.5 = 11.5

x = 11.5/4.75

x = 2.42

Therefore, the maximum number of bags of fruit that Harper can buy is 2 because the number of bags must be whole numbers.

Andru [333]
First we multiply 2r*r and it gives us 2r^{2}. 

Then -5r, + 20r = 15r

Then -5*10 gives us -50.

So the answer is: 2r^{2}+15r-50
