For Each problem, set u a proportion. Include the units for each ratio. Then solve for the missing value and label your answer with appropriate units. Round answers to the nearest tenth.
A 2-month membership to the gym cost $125. Him would like to be a member for 8 months. What is the total amount he will pay for 8 months?
Let x be the total amount he will pay for 8 months.
The ratio of cost per month is 125/2, or 62.5/1, where the units are dollars per month.
Setting up a proportion, we have 62.5/1 = x/8.
Cross multiplying, we get 62.5 * 8 = 1 * x.
Simplifying, we find that x = 500.
Hence, the total amount he will pay for 8 months is $500.
