Question

ICE CREAM The cost of a one-scoop sundae is $\backslash (2.75$, and the cost of a two-scoop sundae is $\backslash )4.25$. Write and evaluate an expression to find the total cost of 3 one-scoop sundaes and 2 two-scoop sundaes.

Step-by-Step Solution

Answer

The total cost of 3 one-scoop sundaes and 2 two-scoop sundaes is $\$16.75$

Step 1. Given information.

The cost of a one-scoop sundae $=\$2.75$

The cost of a two-scoop sundae $=\$4.25$

Step 2. Concept used.

For finding the total cost of 3 one-scoop sundaes and 2 two-scoop sundaes, multiply by 3 with the cost of one-scoop and multiply 2 with the cost of two-scoop sundae and then add both the two terms.

Step 3. To find the total cost of 3 one-scoop sundaes and 2 two-scoop sundaes.

The total cost $=3\left(\$2.75\right)+2\left(\$4.25\right)$

                        $=\$8.25+\$8.5$

                         $=\$16.75$

Therefore,

The total cost of 3 one-scoop sundaes and 2 two-scoop sundaes is $\$16.75$.
