Question

Mr. Schwartz builds toy cars. He begins the week with a supply of 85 wheels, and uses 4 wheels for each car he builds. Mr. Schwartz plans to order more wheels once he has fewer than 40 wheels left. The inequality that can be used to find the number of cars, x, Mr. Schwartz builds before he places an order for more wheels is − x < 40. Mr.Schwartz will need to order more wheels after building cars.

Answer 1

The inequality that can be used to find the number of cars, x, Mr. Schwartz builds before he places an order for more wheels is 4x < 40.

Step-by-step explanation:

To find the inequality that can be used to determine the number of cars, x, Mr. Schwartz builds before he orders more wheels, we need to set up an equation. Mr. Schwartz starts with 85 wheels and uses 4 wheels for each car he builds. So, he can build x number of cars before running out of wheels, which can be represented as 4x. To determine when he needs to order more wheels, we can set up the inequality 4x < 40. This means that Mr. Schwartz will need to order more wheels after building 10 or fewer cars.
