pls help i need to know if this is right i got 7d+50
Lenard practices 7 math problems a day. He has already practiced 50 math
problems this quarter. Write an expression that represents the total number of
math problems he will have practiced in d days.
To get this you take the 7 problems and mulltiply it by d for days. Since he has already done 50 you add the 50 to find how many problems he has completed.
