Translating a Phrase Into a Two-Step Expression

Problem 1

If Sallys age is 20 years less than thrice Mollys age, write a two-step expression to represent the same.

Solution

Step 1:

Let Mollys age be x.

Thrice Mollys age is 3x

Step 2:

20 years less than thrice Mollys age is 3x 20

So the two-step expression representing Sallys age would be 3x 20

Problem 2

If Clara has 10 toys more than twice Capris number of toys, write a two-step expression to represent the same.

Solution

Step 1:

Let Capris number of toys be y.

Twice Capris number of toys = 2y

Step 2:

10 toys more than twice Capris number of toys = 2y + 10

So the two-step expression representing Claras number of toys would be 2y + 10
