at carolina place mall, gina bought a blouse(x), a pair of shoes(y), and a pair of jeans(z). If she paid with a $100 bill, write an expression that represents the amount of change she received.
100 - (x + y + z) = c
To determine the amount of change Gina received, we need to subtract the total cost of her purchases from the $100 bill.
Let's say the cost of the blouse is $x, the cost of the shoes is $y, and the cost of the jeans is $z.
The total cost of Gina's purchases can be calculated by adding up the costs of each item:
Total cost = x + y + z
To find the amount of change Gina received, we subtract the total cost from the $100 bill:
Change = $100 - (x + y + z)
So, the expression that represents the amount of change Gina received is:
Change = $100 - (x + y + z)
