At a baseball game, hot dogs cost $2.25 and drinks cost $1.75. The total cost, t, for h hot dogs and d drinks can be described by the equation t=2.25h+1.75d. If Costas spent $18.25 and bought 5 hot dogs, how many drinks did he buy?

4 drinks

Step-by-step explanation:

t = 2.25h + 1.75d

T = Total Cost

H = Hotdogs

D = Drinks

We have our total cost, which is $18.25 dollars

18.25 = 2.25h + 1.75d

We know Costas bought 5 hotdogs, so replace h with 5 and multiply :

2.25(5)

==> 11.25

Now that 11.25 dollars has been made, let's see how much money we need left to fit for the drinks.

18.25 - 11.25

==> 7

We need 7 dollars worth of drinks, so divide the cost by the amount we need to have.

7 / 1.75

==> 4

Castos needs to buy 4 drinks.

first one because it can't have a fraction in it
