Four friends went to the movies each ticket cost $8 and each person bought popcorn and a soda for $5 how much did they spend in all? let m stand for the amount of money spent

Answer: m = $52

Explanation:

Tickets (t) = $8

Popcorn & Soda (s) = $5

Friends = 4

Since all friends bought the same thing the equation will be set as

4 (t + s) = m OR 4t + 4s = m

Using substitution, you plug each variable

t = 8 and s = 5

4 ((8) + (5)) = m

4 (8+5) = m = > 4 (13) = m = > 52=m

OR

4 (8) + 4 (5) = m = > 32 + 20 = m = >

52 = m
