Answer 2

The poster will be 3.75 feet long.

Explanation:

The photograph is 8 inches wide and 10 inches long

Rusty wants enlarge the photograph to make a poster that is 3 feet wide.

1 foot = 12 inches

3 feet =
`\frac{3 * 12}1}` inches = 36 inches

The enlargement scale factor is 36 inches ÷ 8 inches = 4.5

So the length of the poster will be equal to length of the photograph × enlargement scale factor.

Length of the poster = 10 inches × 4.5 = 45 inches.
