A man has 27 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 525 cents, how many dimes and how many quarters does he have? Your answer is
number of dimes equals=

number of quarters equals=

17(quarters)

10(dimes)

Hi there !

dimes = 0.1$ = 10c

quarters = 0.25$ = 25c

d + q = 27 => d = 27 - q

10d + 25q = 525

replace d

10(27 - q) + 25q = 525

270 - 10q + 25q = 525

25q - 10q = 525 - 270

15q = 255

q = 255 : 15

q = 17(quarters)

d = 27 - q

= 27 - 17

d = 10(dimes)

Good luck !
