Hope I didn't mess up for your sake

Answer 2

First, find the tip amount. Convert the percent to a decimal. Move the % sign two places to the left and then make the % sign into a decimal point.

20% = 0.2

Then multiply 0.2 and 36 together.

0.2 * 36 = 7.2

Then add 7.2 to the cost of the dinner.

7.2 + 36 = 43.20

So, the answer is $43.20.
