Find the total cost of $206.88 with a 5.75% sales tax.

206,88: 94,25 = x: 100

x = (206,88*100) : 94,25

The total cost is $219,50

Steps:

1. Do a proportion

X/$206.88 = 5.75/100

2. Do 206.88 times 5.75 which equals 1,189.56

3. Divide 1,189.56 by 100 which equals 11.89

4. Now do 206.88 + 11.89

5. Your answer is 218.77
