6. Time to practice Page 99 Question 8:
There are three $100 notes and some $10 coins inside a bag. If there are altogether $460, how many $10 coins are there?
Step 1: Let there are x $10 coins.
Step 2: Then, 3 ($100) + x ($10) = $460
Step 3: x = 460
10x = 160
x = 16
Step 4:  There are 16 $10 coins.
