EOC Quiz: Linear Systems and Linear Relationships

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 candles and 8 small candles. The price of each large candle is the same, and the price for each small candle is the same. Which systems of equations can be used to to find the price in dollars for each large candle, x, and each small candle, y?

• $4y=3x+64$ $8y=x+68$

• $8y=x+60$ $4y=3x+64$

• $3x+4y=64$ $x+8y=68$

• $3x+4y=64$ $x+8y=60$
