Kelley spent $2.65 for 15 Sour Keys and 2 Mars bars. Stuart bought 3 Mars bars and 10 Sour Keys for $3.35. What was the cost of a Mars bar? (Hint: The equation for Kelley's purchases is: 158 + 2M = 2.65 First determine the equation for Stuart's purchases, and then solve the system of equations using matrices.)
