Examples
Xochitl buys cheese and potatoes at the
store.
• She pays a total of $53.36.
• She pays $2.88 for the cheese.
• She buys 8 bags of potatoes that each
cost the same amount.
Which equation or tape diagram could be
used to represent the context if ä
represents how much each bag of potatoes
costs?

Answer 1

To find the cost of each bag of potatoes (ä) in Xochitl's purchase, we can use the equation 8ä + $2.88 = $53.36. After subtracting the cost of cheese, we divide the remaining total by 8 to find ä.

Step-by-step explanation:

The question involves creating an equation to represent the total cost of Xochitl's purchase, which includes cheese and potatoes. Since we know Xochitl pays $53.36 in total and $2.88 for the cheese, we can deduce that the rest of the amount was spent on 8 bags of potatoes. If ä represents the cost of one bag of potatoes, then the equation to represent the total cost would be:

8ä + $2.88 = $53.36

To solve for ä, we would subtract the cost of the cheese from the total cost and then divide the remaining amount by 8, as follows:

1. Subtract the cost of cheese from the total cost: $53.36 - $2.88 = $50.48.
2. Divide the remaining amount by the number of bags of potatoes: $50.48 ÷ 8 = ä.

Therefore, the cost of each bag of potatoes (ä) would be calculated to determine the total cost of the potatoes.
