Find the solution by graphing the system of equations.A tour group split into two groups when waiting in line for food at a fast food counter. The first group bought 6 slices of pizza and 5 soft drinks for $26.85. The second group bought 5 slices of pizza and 4 soft drinks for $22.06. We can represent this situation with the system of equations 6p + 5s = 26.85 5p + 4s = 22.06where p is the cost of a slice of pizza and s is the cost of a soft drink. Determine the cost of one slice of pizza.
A. $2.40 per slice of pizza
B. $1.89 per slice of pizza
C. $2.90 per slice of pizza
D. $2.39 per slice of pizza
