Question

Write and solve and equation to find how many movies they have time to show.

We decided that movie night will last four hours. Each movie takes 1.75 hours. And we want to make sure to leave a half-hour for eating popcorn. So how many movies can we show?

Answer 1

Equation 0.5 + 1.75(x) = 4

x = 2movies

Explanation:

Given that,

movie night will last for 4 hours

each movie take 1.75 hours

time for eating popcorn 0.5 hours

To find,

number of movies which can be watched

Equation

0.5 + 1.75(x) = 4

Solve for x

1.75(x) = 4 - 0.5

1.75(x) = 3.5

x = 3.5/1.75

x = 2

So, total number of movies which could be watched in 4hr = 2
