Question

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

Answer 1

a)

To find the increase, you need to find 7% of $45.

so 45 x .07 = 3.15

So the increase is $3.15.

b)

To find the new monthly cost, you need to add $3.15 to $45.

so 3.15 + 45 = 48.15

So the new monthly cost is $48.15.
