Show how you can solve the problem.

HMH Into Math Grade 3 Module 5 Lesson 4 Answer Key Use Multiply Multiples of 10 by 1-Digit Numbers 8

Turn and Talk Suppose one of Darvin’s customers returns a cracked bowl. If Darvin gives her $30 back, will he still have enough for his new wheel? Explain how you know.
Answer:
Given that;
Darvin needs to buy a new pottery wheel = $200
He sold = 7 bowls
Each bowl cost = $30
Therefore 7 bowls × $30 = $210
Darvin has enough money to buy a new pottery wheel.
The customer returns a cracked bowl then Darvin gives her = $30
After returning back $210 – $30 = $180
Now, Darvin has not had enough money to buy a new pottery wheel.
