*In Exercises 17 to 22, use proportions to solve each problem.*

An electrician installs 25 electrical outlets in a new six room house. Assuming proportionality, how many outlets should be installed in a new construction having seven rooms? (Round to nearest integer.)

To determine

**To find:**

The number of outlets that should be installed in seven rooms house.

Explanation

**Approach:**

According to Means-Extremes Property, in a proportion, the product of the means equals the product of the extremes.

**Calculation:**

Let us suppose *x* number of outlets should be installed in the new construction having seven rooms.

It is given that 25 outlets are installed in six rooms house.
