Fuji apples are $1.97 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3-pound bag. If a represents the number of pounds of apples Abigail buys and b represents the number of bananas she buys, which expression represents the amount of change she receives after her purchase?

A. 30.00−(1.79a+0.36b+2.99)
B. 1.79a+0.36b+2.99
C. 30.00−a−b

Answer 1

The expression that represents the amount of change Abigail receives after purchasing apples, bananas, and potatoes is 30.00 - (1.97a + 0.36b + 2.99).

Step-by-step explanation:

Abigail has $30.00 to buy groceries. She plans to purchase Fuji apples, bananas, and a bag of potatoes. The apples cost $1.97 per pound, bananas are $0.36 each, and a 3-pound bag of potatoes costs $2.99. Assuming 'a' is the number of pounds of apples and 'b' is the number of bananas she buys, we must calculate how to express the amount of change she receives after purchasing these items.

The correct way to calculate the change Abigail will receive after her purchases is to subtract the total cost of the groceries from the money she has. Using the provided prices to formulate an expression, we get:

30.00 - (1.97a + 0.36b + 2.99)This expression accounts for the cost of the apples and bananas she buys (with 'a' representing the pounds of apples and 'b' representing the number of bananas), as well as the fixed cost of the potatoes.
