Zoe paid \$18.60$18.60dollar sign, 18, point, 60 in sales tax and tips for her dinner. The sales tax rate is 11\%11%11, percent, and she tipped 20\%20%20, percent. (The sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.)

Sagot :

Answer: 60 dollars

Step-by-step explanation:

Since both the sales tax and the tip apply to the original price of the dinner, we can add the two rates.

11% + 20% = 31%

Next we need to find what number 18.60 is 31% of.

Since percent means per hundred 31% is equal to .31.

Now we need to now what number times .31 + 18.60

Divide both sides by .31.

The .31 will be cancelled out and $18.60 will become $60.

$18.60 is 31% of $60
