CAN YOU PLEASE WRITE THE EQUATION AND THE ANSWERS PLSS 3. You have $20 to spend at the snack bar. All of the
snacks at the snack bar cost $1.25. How much money
will you have left if you buy:
a. 2 snacks?
b. 7 snacks?
c. 12 snacks?

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

Look in the explanation box for the answer :)

Step-by-step explanation:

a)

2 snacks=$2.50    Money left:$17.50

b)

7 snacks=$8.75     Money left:$11.25
