A collection of nickels, dimes, and quarters consist of 9 coins with a total of $1.20. If the number of dimes is equal to the number of nickels, find the number of each type of coins.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
