Question

Betty has a dog walking service. Last year she charged $5.00 per dog for each 1/2 mike. This year, she increases the charge per dog by 5%. how much does she earn this year to walk a dog for 1 and 1/2 miles?

Answer 1

I think it is 2.76 I not really sure but I did 5 times 0.5 which is 2.50 then I multiple it by 5% then I added it with 1 1/2

Answer 2

Last year = $5.00

Increase = 5% of $5
Increase = 0.05 x 5
Increase = $0.25

This year = $5 + $0.25 = $5.25

1/2 mile = $5.25
1 1/2 miles = $5.25 x 3
1 1/2 miles = $15.75

Answer: She earns $15.75 to walk a dog for 1 1/2 miles.
