Jessica went to dinner and her bill was $15.60. If she wants to leave a 15% tip, how much is the tip? How much did she spend total after the tip?

A) $2.34

B) $17.94

Step-by-step explanation:

First in order to find the tip you need to set up a proportion:

15/100 = x/15.6

Step 1: Cross-multiply.

15/100 = x/15.6

(15)*(15.6) = x*(100)

234 = 100x

Step 2: Flip the equation.

100x=234

Step 3: Divide both sides by 100.

100x/100 = 234/100

x = 117/50 (2.34)

The tip is $2.34

Now to find the total, add the tip to the bill.

15.6+2.34

= 17.94

The total bill was $17.94
