Final answer:

To find out how long it will take Roscoe to save $112.50, we can set up a proportion using the given information. The solution is 9 months.

Step-by-step explanation:

To find out how long it will take Roscoe to save $112.50, we can set up a proportion using the given information. We know that Roscoe saves $50 in 4 months. So, the ratio of the amount saved to the time it takes is $50/4 months. We can set up a proportion with the unknown time and amount: $112.50/x months = $50/4 months.

To solve the proportion, we cross-multiply and solve for x:

$112.50 * 4 months = $50 * x months

$450 = $50 * x months

Dividing both sides of the equation by $50, we get:

x months = $450/$50

x months = 9 months.

It will take Roscoe 9 months to save $112.50
Divide 50 by 4 to get the amount he saves monthly. It should be 12.5
Now divide 112.5 by 12.5 to get the amount of months it will take to reach that amount of money to save.
Your answer should be 9.
Hope I helped!
