15 • 25 − 75x
Part A: What does 375 represent?
Part B: What does the 75x represent?
Part C: What does the entire expression represent?

Answer 1

Part A. Remember that 15 is the dosage of 1 pill and 25 is the total number of pills
so 15*25 basically means
(single dose)*(number of pills)=?
Part B. x usually means a variable that changes and affects other things, also remember that her parrot was prescribed 75 mg every day
