Work Step by Step
Students majoring in philosophy earn $\$43,000$ per year.
Students majoring in accounting earn $\$63,000$ per year.
We can find the increase in average yearly earnings.
$\$63,000 -\$43,000 = \$20,000$
We can express this increase in average yearly earnings as a decimal of the average yearly earnings for students majoring in philosophy.
$\frac{\$20,000}{\$43,000} = 0.465$
To express a decimal as a percent, we can move the decimal point two places to the right.
$0.465 = 46.5\%$
The percent increase in average yearly earnings is 46.5%
