A baker sells a dozen donuts for \(\$3.99\). The cost to make three donuts is \(\$0.45\). How much is the total profit on 5-dozen donuts?

\(\$10.95\)

Explanation

Multiply \(\$0.45 \)(the cost of making 3 donuts) by 4 to find the cost of making a dozen donuts: \( \$0.45 \times 4 = \$1.80\). Then multiply the cost of making a dozen donuts by 5 to determine the cost per 5 dozen: \(\$1.80 \times 5 = \$9.00\). Next, multiply the selling price per dozen times 5, the number of dozens sold: \(\$3.99 \times 5 = \$19.95\). Finally subtract the cost of making 5-dozen donuts from the price the baker sells them for to determine the profit: \(\$19.95 – \$9.00 = \$10.95\).
