Final answer:
Paul and Tisha would each sell 11 subscriptions and earn $48.
Step-by-step explanation:
To find out how much Paul and Tisha would earn and how many subscriptions they would sell in order to earn the same amount, we can set up equations for both of them. Let's say they each sell x subscriptions in an hour:
Paul's earnings = base wage + (number of subscriptions sold * amount earned per subscription)
P = 15 + (x * 3)
Tisha's earnings = base wage + (number of subscriptions sold * amount earned per subscriptions)
T = 4 + (x * 4)
Since they earn the same amount, we can set the two equations equal to each other:
15 + (x * 3) = 4 + (x * 4)
Combine like terms and isolate x:
3x - 4x = 4 - 15
-x = -11
x = 11
So they would each sell 11 subscriptions and earn $48.
