Answer:

a. $17.50

b. $11.25

c. $5

Step-by-step explanation:

First, set up an equation:

20 - 1.25x = m

Now let's substitute in for x (which is how many snacks you buy) to solve for m (the amount of money you have left):

20 - 1.25 ( 2 ) = m

20 - 2.50 = m

17.50 = m

20 - 1.25 ( 7 ) = m

20 - 8.75 = m

11.25 = m

20 - 1.25 ( 12 ) = m

20 - 15 = m

5 = m
