Abigail has $30.00 to buy groceries. She needs to buy some apples, some bananas, and 3 pounds of potatoes. Fuji apples are $1.79 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3 lb. 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 purchases?
The expression that best describes her change may be found by constructing the mathematical equation that describes the situation.
Since a represents the number of apples, b represents the number of bananas, we let c represent her change. Hence,
30=1.79a+0.36b+2.99+c
rearranging the terms to solve for c,
c=30-2.99-1.79a-0.36b
c=-1.17a-0.36b+27.01
