A family pays $ 45 each month for cable TV. The cost increases 7%.

Question

How many dollars is the monthly increace?

What is the new monthly cost.

Answer 1

The initial cost is $45. To determine the increase, you need to follow two steps.

 

First you have to find what 7% of the original $45 is. This will tell us how much the cost will increase by.

To find 7% of $45, you need to multiply .07 x 45 = 3.15

This tells us that 7% of $45 = $3.15

 

Next, you have to add the increase to the original cost. This will be the new monthly cost.

$45 + $3.15 = $48.15
