Question

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

you go shopping and spend 50% of the total number of quarters. Write an expression to represent the
total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you
have left.

Answer 1

Answers:

Expression for the total number of quarters is 40*1.20

Amount of money you have left is 6 dollars

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

Step-by-step 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.
