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 $27.52. The second group bought 5 slices of pizza and 4 soft drinks for $22.64. We can represent this situation with the system of equations 6p + 5s = 27.52 5p + 4s = 22.64where 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. $2.26 per slice of pizza B. $3.12 per slice of pizza C. $1.76 per slice of pizza D. $2.62 per slice of pizza
