Chapter 8 - Personal Finance - 8.1 Percent, Sales Tax and Discounts - Exercise Set 8.1: 47

Answer

(a) $tax = \$1968$ (b) The car's total cost is $\$34,768$

Work Step by Step

(a) To express a percent as a decimal, we can move the decimal point two places to the left. $tax~rate = 6\% = 0.06$ We can calculate the tax. $tax = (0.06)(\$32,800)$ $tax = \$1968$ (b) We can calculate the total cost. $cost = \$32,800 + \$1968$ $cost = \$34,768$ The car's total cost is $\$34,768$
