The following expression represents the total amount Robert will spend after buying x baseballs.

If the cost of each baseball, m dollars, is tripled, then the value of b will_______________ and the value of mx will ________________________.

Answer 1

Answer:

Step-by-step explanation:

Let x represent the number of baseballs that Robert brought. The cost of each baseball is m dollars. This means that the cost of x baseballs will be $mx

The following expression represents the total amount Robert will spend after buying x baseballs.

Total amount = mx + b

If the amount already spent by Robert on other equipment, b dollars, is doubled, then the value of m will remain the same.

If the cost of each baseball, m dollars, is tripled, then the value of b remains the same and the value of mx will be 3mx
