Question

Scott and his wife Maria have cell phone plans in which they pay for each call minute and text message they send. Last month, Scott used 95 call minutes and sent 207 text messages for $23.55. Maria used 162 call minutes and sent 124 text messages for $17.26. Find the cost for each call minute.

Answer 1

To find the cost for each call minute, set up a system of equations and solve for x and y. The cost per call minute for Scott is approximately $0.087, and the cost per call minute for Maria is approximately $0.072.

Step-by-step explanation:

To find the cost for each call minute, we can set up a system of equations using the given information. Let's assume the cost per call minute for Scott is x and for Maria is y. The total cost for Scott is 95x + 207y = $23.55, and the total cost for Maria is 162x + 124y = $17.26.

Using these equations, we can solve for x and y. After solving, we find that the cost per call minute for Scott is approximately $0.087, and the cost per call minute for Maria is approximately $0.072.
