Lisa dined at a restaurant and gave the waiter a 15% tip if the price of her meal was $10.25 how much did lisa tip the waiter

Multiply the price of her meal by the percentage of the tip.

15% = 0.15

Tip = 10.25 x 0.15 = 1.54

The tip was $1.54

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30
