The percent increase in average yearly earnings is 100%

Work Step by Step

Students majoring in social work earn $\$38,000$ per year. Students majoring in engineering earn $\$76,000$ per year. We can find the increase in average yearly earnings. $\$76,000 -\$38,000 = \$38,000$ We can express this increase in average yearly earnings as a decimal of the average yearly earnings for students majoring in social work. $\frac{\$38,000}{\$38,000} = 1.0$ To express a decimal as a percent, we can move the decimal point two places to the right. $1.0 = 100\%$ The percent increase in average yearly earnings is 100%.
