Question

You have 40 quarters. You find 20% more quarters in your room. Then

Answer 1

Answers:

Expression for the total number of quarters is 40*1.20

Amount of money you have left is 6 dollars

===================================================

Explanation:

You start with 40 quarters. 20% of this is 0.20*40 = 8 which means you found 8 more quarters. The total goes from 40 to 40+8 = 48.

A slight shortcut is to write 40*1.20 = 48

--------------

48 quarters = 48*0.25 = 12 dollars

Or you can divide by 4 to determine the total value of the quarters in dollars.

If you spent half (50%) of that money, then you'll be left with 6 dollars.
