I need to find the total cost.
A meal is $32 with 5% sales tax and 20% tip.

A meal is $32. So now you have to take 5% of that meal, which means you convert 5 percent to a decimal. To change 5.0% to a decimal, you move the decimal two places to the left. So 5.0% becomes: .05 as a decimal.

Now let's multiply:
32+%2A+.05+=+1.60 Therefore, the tax on the meal was $1.60.

Now let's figure a 20% tip. You have to take 20% of the meal, which again means you have to convert a percentage (in this case 20%) to a decimal. To change 20.0% to a decimal, you move the decimal two places to the left. So, 20.0% becomes: .20 as a decimal.

Now let's multiply again:

32+%2A+.20+=+6.40 Therefore, the tip for the meal was $6.40


Now we just add all this up:

$32.00 (cost of meal)
1.60 (5% tax)
6.40 (20% tip)

$40.00 TOTAL
