Only one question should be provided, we will answer question #1 and also note that question #2 contains errors, apparently a typo.
Ace has $3.15 nickels and dimes. He has 15 more nickels than dimes. How many each type of coin does he have?
Let 'd' represent the number of dimes, then 'd+15' represents the number of nickels.
A dime is "0.10" and a nickel is "0.05".
3.15 = 0.10d + 0.05(d+15)
