Example 4: Expressions from Word Problems
It costs Margo a processing fee of $3 to rent a storage unit, plus $17 per month to keep her
belongings in the unit. Her friend Carissa wants to store a box of her belongings in Margo’s
storage unit and tells her that she will pay her $1 toward the processing fee and $3 for every
month that she keeps the box in storage. Write an expression in standard form that
represents how much Margo will have to pay for the storage unit if Carissa contributes. Then,
determine how much Margo will pay if she uses the storage unit for 6 months.
Marking the text:
Margo's expression:
Carissa's expression:

Complete with partner (card match)
Mul plica ve inverses have a product of 1. Find the mul plica ve inverses of
the terms in the first column. Show that the given number and its
mul plica ve inverse have a product of 1. Then, use the inverse to write each
corresponding expression in standard form. The first row is completed for
you.

Expressions and Equa ons
December 27, 2015
7.EE
Use properƟes of operaƟons to generate equivalent expressions.
1. Apply proper es of opera ons as strategies to add, subtract, factor, and expand linear
expressions with ra onal coefficients.
2. Understand that rewri ng an expression in different forms in a problem context can shed
light on the problem and how the quan es in it are related. For example, a + 0.05a = 1.05a
means that “increase by 5%” is the same as “mulƟply by 1.05.”
LT: I will learn how to write equivalent expressions.
EQ: How can I use expansion and combining like terms to write equivalent expressions?
