Todd · Answer 1

20/100 = x/12

The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The / 12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.

x = $2.40

The total cost would be $2.40 + $12.00 = $14.40
