Part A:
Coefficient is a number that shares with a variable.   So a coefficient is 8 or 75.   A constant is a whole number like 25.   A variable is w or d.

Part B:
5 x 75 = 375.   8 x 48 = 384.   So add 375 and 384 and you get 759.  He made 759 dollars.

Part C; The constant would change.





All done.   Hope this helps.    Mind meddling or fanning me?
