Question

Enrique took his brother out

to dinner to celebrate. He
decided to leave a 25% tip
because the service was
excellent. The tip was
$18.10. How much was the
original bill?

Answer 1

72.4$

Explanation:

We can use cross multiplication here

`(18.10)/(originalbill) = (25)/(100)`

18.10 x 100 = 25 x original bill

1810 = 25 x original bill

72.4 = original bill
