Yes, you have enough money to pay for the piece of candy.
Three quarters are equal to $0.75 (0.25 x 3 = 0.75), two dimes are equal to $0.20 (0.10 x 2 = 0.20), and three nickels are equal to $0.15 (0.05 x 3 = 0.15).
Adding these amounts together, you get:
0.75 + 0.20 + 0.15 = 1.10
So you have $1.10, which is more than enough to pay for the $1.59 piece of candy.
