Taminka received a raise in her hourly pay, from $13.50 to $14.99. Find the percent change. Round to the nearest percent.
polet [3.4K]

Answer:

\% = 11\%

Step-by-step explanation:

Given

Initial = \$13.50

Final = \$14.99

Required

Determine the percentage change

This is calculated as:

\% = |\frac{Initial - Final}{Initial} * 100\%

\% = |\frac{13.50 - 14.99}{13.50}| * 100\%

\% = |\frac{-1.49}{13.50}| * 100\%

\% = \frac{1.49}{13.50} * 100\%

\% = \frac{1.49* 100\%}{13.50}

\% = \frac{149\%}{13.50}

\% = 11.037037037\%

\% = 11\%
