Question

1. 7.EE.B.4

Bob buys eggs and potatoes at a store.
• He pays a total of $25.92.
• He pays $2.57 for the eggs.
• He buys 5 bags of potatoes that each cost the same amount,
Which equation can be used to determine the cost, x, of each bag of potatoes?
A
1
= (25.92 - 2.57) = 5
B
x = 25.92 = 5 + 2.57
X = (25.92 +2.57) = 5
D
x = 25.92 - 5 -2.57

Answer 1

I believe that A is the correct answer because this is how I would normally solve the equation. X representing the unknown cost of each bag of potatoes.

Answer 2

x = (25.92 – 2.57) = 5

Explanation:

Bob bought eggs and potatoes at a store.

He pays a total of $25.92 for both the egg and potatoes

He pays $2.57 for the eggs.

He buys 5 bags of potatoes that each cost same amount. The equation that can be used to determine the cost of x, of each bag of potatoes can be calculated as follows:

Let

number bag of potatoes = x

The cost of the whole potatoes he bought = $(25.92 - 2.57)

The cost of the whole potatoes he bought = $23.35

The cost of 1 bag of potatoes(x) = (25.92 - 2.57)/5

x = (25.92 - 2.57)/5

it is same as

x = (25.92 – 2.57) = 5
