Problem

Allam just finished a great meal at a restaurant in Wisconsin. The sales tax in Wisconsin is $5\%$5, percent, and it is customary to leave a tip of $15\%$15, percent for the server. The tip amount is calculated on the price of the meal before the tax is applied. (Sales tax is not calculated on tips.)

If Allam ordered a $\$15$dollar sign, 15 meal, how much money will he have to pay with tax and tip?

$\$$dollar sign 

Hint #11 / 4

We have to add the $\red{5\%}$start color #df0030, 5, percent, end color #df0030 tax and the $\green{15\%}$start color #28ae7b, 15, percent, end color #28ae7b tip to the basic price of the meal, $\blue{\$15}$start color #6495ed, dollar sign, 15, end color #6495ed.

Hint #22 / 4

The tax adds $\red{5\%}$start color #df0030, 5, percent, end color #df0030 to the price of the meal, and the tip adds $\green{15\%}$start color #28ae7b, 15, percent, end color #28ae7b so the total amount Allam has to pay is $\purple{20\%}$start color #9d38bd, 20, percent, end color #9d38bd more than the price of the meal.

Hint #33 / 4

Adding $\purple{20\%}$start color #9d38bd, 20, percent, end color #9d38bd to an amount is the same as multiplying the amount by $\purple{1.20}$start color #9d38bd, 1, point, 20, end color #9d38bd.

Hint #44 / 4

The price with tax and tip is $\purple{1.2} \times \blue{\$15}=\$18$start color #9d38bd, 1, point, 2, end color #9d38bd, times, start color #6495ed, dollar sign, 15, end color #6495ed, equals, dollar sign, 18.
