Question

The price of a notebook has risen to $3.70 today. Yesterday's price was $3.20 . Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

Answer:

16%

Step-by-step explanation:

Equation: $\frac{new value-old value}{old value}$ * 100

$\frac{3.70-3.20}{3.20}$* 100= $\frac{0.50}{3.20}$* 100

0.15625 (round to .16)

16%
