there are
23 quarters
37 dimes
to do this use simultaneous equations
to make this simpler i will assign variables to amount of quarters and dimes
x-quarters
y-dimes
you know you have 60 coins, so amount of quarters plus dimes is 60
x+y=60
you also know the amount is equal to $9.45
since quarters are $0.25 and dimes are $0.10 another equation can be made
0.25x+0.10y=9.45
this equation shows what you do when you count your change
now solve the first equation for a variable using algebra
x=60-y
you can then plug this new value into your second equation
0.25(60-y)+0.1y=9.45
you can now solve for y, which is the number of dimes
y=37
now plug this number back into x=60-y to get the amount of quarters
x=60-(37)
x=23
23 quarters
37 dimes
There are three possible combinations: 1 quarter and 13 dimes 3 quarters and 8 dimes 5 quarters and 3 dimes
30 quarters equals $7.50 42 dimes equals $4.20 That adds up to 72 coins with a value of $11.70
16 % of the coins are dimes. 4 of a total of 25.
Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
5 dimes 2 quarters
If 5 dimes to every 8 quarters that is 5 out of every 13 coins dimes and 8 of 13 coins quarters 5/13 x 520 = 200 dimes
If Keoki has 14 quarters and 8 dimes (for a total of 22 coins), she has $3.50 and $0.80 or $4.30 in coins. If Keoki has 15 quarters and 7 dimes (for a total of 22 coins), she has $3.75 and $0.70 or $4.45 in coins. If Keoki has 22 coins that are all dimes and quarters and their value in total is $4.35 as asked, there isn't a combination of coins that will permit her to have both 22 coins and $4.35 worth of coins.
Mula has 16 dimes and 11 quarters.
There are three possible combinations: 1 quarter and 13 dimes 3 quarters and 8 dimes 5 quarters and 3 dimes
The man has 13 dimes and 7 quarters, which equate to $3.05 $1.30 + $1.75 If he had 13 quarters and 7 dimes he would have $3.95 $3.25 + 70c The method used to work this out was dividing 90c by the difference between the value of a dime and a quarter- i.e. 15c . 90 / 15 = 6, so of 20 coins, 6 more were dimes than quarters. Subtract 6 from 20, then halve the result = 7 the lower number is 7, the higher number is 7+6, = 13. Please also note that 'Quarters' is spelled with 2 'r's
30 quarters equals $7.50 42 dimes equals $4.20 That adds up to 72 coins with a value of $11.70
