I’m pretty sure it’s linear!
For the question in the photo:
y = 2.50x + 7.50
Domains:
0, 2, 3, 4, 5, 6, 7, 8, 9, 10
As you can’t ride 0.2 or 0.7 of a ride, for example, and you only have time for ten rides. Plus you have enough money to ride ten rides
For the drama club one:
C = 21t + 40
Is the correct answer as 40 is a set value and is not influenced by the amount of club members there are, x is the amount per shirt, and C is the cost
Divide the annual salary by 12 and you'll find the monthly salary
month salary = annual salary/12
month salary = 52,750/12
month salary = 4,395.83
Her monthly salary is $4,395.83
