Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. he spent a total of $47.65. if hugh bought 3 magazines, how many books did he buy ?

He bought 4 books

Steps:

3.95(3) + 8.95b = 47.65
11.85 + 8.95b = 47.65

Now just subtract 11.85 from both sides and now the equaton shoud look like this

8.95b = 35.8

Now divide 8.95 from both sides and you get...

b=4

Hope this helps!

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
