Question 13 • GA-Advanced Algebra: Concepts and Connections CR

A photographer has a print that is 3.5 inches wide and 2.5 inches tall. If the photographer enlarges the print so that it is 7 inches wide, how tall will it be?

Answer
A
5 inches
B
6 inches
C
8 inches
D
12 inches

Explanation

The enlargement keeps the print’s proportions the same. The width doubles from 3.5 inches to 7 inches, so the height doubles too: 2.5 × 2 = 5 inches. The enlarged print will be 5 inches tall, which is choice A.
