Carly got her haircut for $45.60 she wants to tip her hair dresser 15% what is her total paid?

egoroff_w [7]

Answer:

$52.44

Step-by-step explanation:

Long method:

1. Convert the percentage into a decimal (15/100 = 0.15)

2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)

3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)

Quicker Way (easier w/ a calculator)

1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)

2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)

In a single equation, it would be

$\frac{115}{100} \times 45.60 = 52.44$
