Question

Ally and Beth are at the grocery store. Ally buys a container of milk for $4 and 4.75 pounds of apples. Beth buys a box of cereal for $3 and 5.55 pounds of apples.

Solve for ‘a’ to determine how much 1 pound of apples costs if both shoppers spent the same amount.

4 + 4.75a = 3 + 5.55a

Answer 1

Explanation step by step:

Rearrange the term’s 4.75a-5.55a =3-4

Combine like terms-8a=3-4

Divide both side of the equation by the coefficients of variables a=-1/-0.8

Calculate a=5/4

Correct answer a=5/4

Answer 2

4 + 4.75a = 3 + 5.55a
4 - 3 = (5.55 - 4.75)a
1 = 0.8a
a = $1.25 [A.]
