$130.00
There are 40 quarters to a roll, which equals $10.00
8 quarters, 5 dimes
13 and 2 quarters as a decimal = 13.51 quarter = 1/42 quarters = 2/4 or 1/2 = 0.5thus, 13 + 0.5 = 13.5
13 quarters
There are 13 quarters in: 3 1/4
6 and three quarters is.
8 of them.
13 what- it could be 13$ 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
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
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.
There are 52 quarters in 13 dollars.
13 quarters
13 and 2 quarters as a decimal = 13.51 quarter = 1/42 quarters = 2/4 or 1/2 = 0.5thus, 13 + 0.5 = 13.5
If you start with 30 nickels, you have $1.50. Every time you replace a nickel by a quarter, you gain 20 cents. $4.10 is $2.60 more than $1.50, so you need 13 quarters, leaving 17 nickels. Check: 13*0.25 + 17*0.05 = 3.25 + 0.85 = 4.10.
