Question

Ms. Sharp is going to a bakery to pick bread to bring to a family dinner. She also purchases a pie for $15. If each loaf of bread costs $8, write an equation to represent the total cost, y, of x loafs of bread and the pie from the bakery.

Answer 1

y = 15 + 8x

Explanation:

Let us call x the number of loaves of bread bought. If each loaf costs $8, then the cost of x loaves is 8x. Adding the cost of the pie ($ 15) gives

`15+8x`

which is the total cost y of the purchase; therefore, we can say

`y=15+8x`
