A vending machine has nickels and dimes. The vending machine has 32 coins in total, with a value of $2.60. What equation models the scenario?
n + d = 32
.05n + .10d = 2.60
n + d = 2.60
.05n + .10d = 32
n + d = 32
.10n + .25d = 2.60
n + d = 2.60
.10n + .25d = 32

A piggy bank has dimes and quarters. The piggy bank has 25 coins, and has a value of $4.90. What system of equations models this scenario?
d + q = 25
.10d + .25q = 4.90
d + q = 4.90
.10d + .25q = 25
d + q = 25
.05d + .10q = 4.90
d + q = 4.90
.05d + .10q = 25

You sell 15 rolls of wrapping paper for a fundraiser. Shiny wrapping paper costs $4 and regular wrapping paper costs $2. The total for the 15 rolls was $44. Which system of equations represents the situation?
x + y = 15
4x + 2y = 44
4x + 2y = 15
x + y = 44
x = 2y + 44
4x = y + 15
2x - 4y = 44
x - y = 15

A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same.
Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y?
4y = 3x + 64
8y = x + 68
4y = 3x + 64
8y = x + 60
3x + 4y = 64
x + 8y = 68
3x + 4y = 64
x + 8y = 60

x = y + 22
x + y = 22
y = x - 22
2x + y = 22
x = y + 60
