Work Step by Step

Find the amount of the increase by multiplying the base (starting salary) by the rate. $\$22.15\times32\%=\$22.15\times0.32=7.088$ Since the digit to the right of the cents digit is greater than 5, round up. The increase will be \$7.09. Add to the original salary to find the new salary, $\$22.15+\$7.09=\$29.24$
