In chad's reading class, all the students are reading the same book. the school bought each student a book at $7 per book. if there are 27 students in chad's class, which of the following expressions could not be used to calculate the total cost? 7(30) - 7(7) 7(20) + 7(7) 7(30) - 7(3)

c-4 is the final answer! : )

step-by-step explanation:

if graphs are part of the problem statement, share them.   .
