Question

Jovan needs to buy a package of ham for $5, a package of cheese for $3, and a loaf of bread for $4 to make lunch.

Answer 1

Answer:

3+4+5

Step-by-step explanation:

The equation: (1−x)3+(1−y)4+5, applies if he uses cheese and bread coupons.

The equation: (1−z)(3+4+5), applies if he uses total purchase discount.

Jovan cannot combine the coupon for the total purchase with the other two coupons. So, if the total discount is applied then the expression (3+4+5) represents the price of the ham, the cheese, and the bread before the discount is applied.

Answer 2

the answer should be the 3+4+5
