Question

The width of a woman's shoulders is proportional to her height. A woman who is 64 inches tall has a shoulder width of 16.2 inches. Find the height of a woman who has a shoulder width of 18.5 inches.

Answer 1

Set up a proportion:

`(64)/(16.2) = (x)/(18.5)`

Cross multiply:

`(64*18.5) = 16.2x`

Simplify:

`1184 = 16.2x`

Solve for x:

`x = (1184)/(16.2)`

Simplify:

`x = 73.1`
