$130.00
There are 40 quarters to a roll, which equals $10.00
8 quarters, 5 dimes
13 quarters
There are 13 quarters in: 3 1/4
Well, isn't that just a happy little math problem! 13 whole dollars is the same as 13.00 in decimal form. And if we add 2 quarters, that's 0.50 more. So, 13 dollars and 2 quarters is 13.50 in decimal form. Just imagine all the beautiful things you could buy with that!
6 and three quarters is.
8 of them.
13 what- it could be 13$ then it would be a better question- we need moreinfo
8 quarters, 5 dimes
If all coins were dimes he would have $1.30. Every quarter that replaces a dime increases the total by 15c. The total has to be increased by $1.20 which is 15c x 8. He has 8 quarters and 5 dimes.
$3.45 $1.00 = 4 quarters $2.00 = 8 quarters $3.00 = 12 quarters $3.00 + $0.25 + $0.10 + $0.10
Well, let's think about this in a happy little way. If you have 52 quarters, each worth 25 cents, you can multiply 52 by 25 to find the total amount. That would give you 1,300 cents, which is $13. So, you have $13 in 52 quarters. Just imagine all the beautiful things you could do with that!
Quarters = xDimes = 13 - x(.25)x + (.10)(13 - x) = 2.50.25x + 1.3 - .1x = 2.5.15x + 1.3 = 2.5.15x = 1.215x = 120x = 120 / 15x = 88 quarters = $2.005 dimes (13 - x) = $0.50Total = $2.50
There are 52 quarters in 13 dollars. This is because there are 4 quarters in every dollar, so by multiplying 13 dollars by 4 quarters, you get 52 quarters.
Note that a quarter is 25 cents or $0.25. Multiply that value by 13 to obtain $3.25.
The first step in solving this problem is to build two equations. 0.25Q+0.10D=2.50 and Q+D=13 where Q=total number of quarters and D=total number of Dimes. Next we try to subtract one equation from the other to eliminate one variable. So we multiply 0.25Q+0.10D=2.50 by 4 to get 1Q+0.4D=10. Then we subtract Q+0.4D=10 from Q+D=13. This results in 0.6D=3. We divide both sides by 0.6 and end up with d=5. Therefore we have 5 dimes, which equals 50 cents. Therefore we have $2 in quarters or 8 quarters. 8 quarters is the answer.
In three and a quarter, there are 13 quarters. This is because each whole number represents four quarters, and the additional quarter in three and a quarter adds one more quarter, totaling 13 quarters.
