Question

Sam has 43 pencils. Abby has twice as many pencils as Sam. How many pencils do they have altogether?

Answer 1

129

Explanation:

Sam = 43 (s)

Abby = 2s

s + 2s = 3s

3s, when s = 43, equals 129

Answer 2

86 altogether.

Explanation:

Since she has twice as many, you would do 43 x 2 = 86
