375 divided by 7.5 is 50

50 time 3 is 150

A used book store about $500 dollars worth of books they sold the books for $1,200 making $7.00 per book how many books were involved

profit from each book = $7
Number of books = total profit/ profit per book = $700/$7 = 100

So there were 100 books.

4+6(7-m)=4 solve for m

Answers

4+6(7-m)=4
Opening the brackets;
4+42-6m=4
46-6m=4
Putting like terms together;
46-4=6m
42=6m
m= $(42)/(6)$
m=7

4-4+42-6m=0
42=6m
m=42/6
m=7
