Question

1. (equations) 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 $x = (25.92 - 2.57) \div 5$
b $x = 25.92 \div 5 + 2.57$
c $x = (25.92 + 2.57) \div 5$
d $x = 25.92 \div 5 - 2.57$
\bigcirc a
\bigcirc b
\bigcirc c
\bigcirc d

Explanation:

Step1: Find total cost of potatoes

Total payment is $25.92, eggs cost $2.57. So potatoes cost is $25.92 - $2.57.

Step2: Find cost per potato bag

There are 5 bags, so cost per bag \( x = \frac{25.92 - 2.57}{5} \), which matches option A.

Answer:

A. \( x = (25.92 - 2.57) \div 5 \)
