Question

Martina has $15 to spend. She spent $5.50, including tax, to buy a notebook. She needs to save $7.75, but she wants to buy a snack. If cookies cost $0.25 per package including tax, what inequality would show the maximum number of packages that Martina can buy? Solve your inequality by showing your work and steps.

Answer 1

Answer:

6

Step-by-step explanation:

15 - 5.50 - 7.75

= 1.75 (This is how much she can spend on cookie packages)

Let x represent the number of cookie packages Martina can buy.

1.75 > 0.25x

1.75/0.25 > 0.25x/0.25

7 > x

Since x must be LESS THAN 7,

Therefore Martina can buy a maximum of 6 cookie packages.
