1.A photography company wants to put your pose on a billboard. The height from the base of your neck to the top of your head is 20 inches, but on the billboard, the height increases to 75 inches.

Answer 1

The length from one shoulder to the other on the billboard would be 67.5 inches.

Answer 2

## Step 1This problem involves the concept of proportionality. The height of the person's pose is increasing from 20 inches to 75 inches. This is a 3.75 times increase (75 divided by 20). ## Step 2Since the billboard is a proportional enlargement of the person's pose, the length from one shoulder to the other would also increase by the same factor of 3.75.## Step 3To find the new length on the billboard, we multiply the original length (18 inches) by the factor of 3.75.### **Formula**: The new length = Original length * Factor of increase## Step 4Substitute the given values into the formula:New length = 18 inches * 3.75
