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.

If you're talking about #3, then the equation would be 10+12.50h=5+15h.
h will equal 2, and the cost for that number of hours would then be $35.
Solve for the bracelet first.
x represents number of beads for bracelet
So it would be number of beads for the bracelet + number of beads for necklace (5x) and they both equal 192
x + 5x = 192
Then you would add the x and 5x.<br />6x = 192
Now all you have to do is divide by 6 on both sides.
6× ÷ 6 = 192 ÷ 6
You know have the number of beads it takes for a bracelet.
x = 32
to get the necklace all you need to do is multiply it by 5 because you need 5 times more for the necklace.
32 × 5
total beads needed is 160.
160
x+5x=192
6×=192
6x÷6=192÷6
x=32
necklace needs 32x5
beads per necklace is 160
