pasha has box with 40 coins consisting of dimes, quarters and nickels that are worth $5.25. there are 5 more nickels than quarters. how many of each coin does she have?

15 Quarters, 20 Nickels, and 5 Dimes

Step-by-step explanation:

Dimes = y

Quarters = x

Nickels = x+5

y:

2x+5+y=40

y=35-2x

Solve:

5 (x+5) + 25 (x) + 10 (y) = 525

Substitute y:

5 (x+5) + 25 (x) + 10 (35-2x) = 525

30x+25+350-20x=525

10x=150

x=15
