Roy bought \(\$34.15\) worth of materials at the hardware store. A sales tax of 6 percent was added on. What was the final cost?

Explanation

To find the sales tax, find 6% of \(\$34.15\). That's the same as \(0.06 \times \$34.15\), which equals \( \$2.0490\). The sales tax rounds off to \(\$2.05\). Add it to the cost before tax to get the total: \(\$34.15 + \$2.05 = \$36.20.\)
