Question

Last summer, Marion was 3 1/2 feet tall. She was 4 inches taller than her brother Elijah. She was 1 1/4 feet shorter than her sister Lorie. How tall were Elijah and Lorie last summer?

Answer 1

Marion's height = 3 1/2 feet = (3 x 12) + 6 = 42 inches

Let's use "E" to represent Elijah's height in inches. Then, according to the problem:

Marion's height = E + 4 inches (since she was 4 inches taller than Elijah)

And:

Lorie's height = Marion's height + 1 1/4 feet = 42 + (1 x 12) + 3 = 57 inches

Now we can use the first equation to solve for Elijah's height:

E + 4 = 42

E = 42 - 4

E = 38 inches

Therefore, Elijah's height last summer was 38 inches, and Lorie's height was 57 inches.
