Robert is purchasing some equipment for his baseball team. he wants to buy some baseballs, each priced at m dollars. he has already spent b dollars on other equipment.

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

if the amount already spent by robert on other equipment, b dollars, is doubled, then the value of m .

if the cost of each baseball, m dollars, is tripled, then the value of b and the value of mx will

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

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
