d = q + 3; 10d + 25q = 345. 10(q + 3) + 25q = 345 ie 35q = 315 so q = 9 and d = 12. Check: 9 quarters = $2.25, 12 dimes = $1.20, total $3.45.QED
7 quarters 2 dimes 4 nickels
15 quarters, 3 dimes
He has 18 quarters (for $4.50)...........and 10 dimes ($1.00)
Well, honey, if we're talking about quarters and dimes, there are actually 6 ways you can make $2.00. You can have 8 quarters and 0 dimes, 6 quarters and 2 dimes, 4 quarters and 4 dimes, 2 quarters and 6 dimes, 0 quarters and 10 dimes, or just a fancy mix of quarters and dimes. So, go ahead and make it rain with those coins!
To make $2.50 from quarters (worth 25 cents) and dimes (worth 10 cents), we can set up a system of equations. Let q represent the number of quarters and d represent the number of dimes. The equations would be 25q + 10d = 250 (representing the total value in cents) and q + d = 25 (representing the total number of coins). Solving these equations simultaneously, we find that there are 6 ways to make $2.50 using quarters and dimes.
The answer is 32 quarters
7 quarters 2 dimes 4 nickels
30 quarters equals $7.50 42 dimes equals $4.20 That adds up to 72 coins with a value of $11.70
10 dimes 5 quarters
15 quarters, 3 dimes
130 quarters are in 325 dimes
