Question 682827: I need help in this problem, thank you
Sue took her collection of nickels and dimes to deposit in the bank. She has five fewer nickels than dimes. Her total deposit was $55.40. How many dimes did she deposit?

.05x + .1y = 55.40 ⇒ x is nickles and y is dimes
x = y-5 ⇒ less nickles, more dimes
.05(y-5) + .1y = 55.40 ⇒ substituting and solving for y as the question asks for dimes ye
.05y - .25 + .1y = 55.40
.15y = 55.40 + .25
.15y = 55.65
y = 371 dimes
