A student works two different jobs. At the first job, they earn $8.50 per hour working at a fast
food restaurant. At their second job, they are paid $25 to take care of landscaping at their
neighbor’s house once a week. Write a function rule showing that the amount the student
earns, (ℎ), depends on the number of hour worked, ℎ, and use it to determine how much the
student earns each week. Then evaluate the expression to determine how much the student will
earn next week if they are scheduled to work 12 hours and 45 minutes at the restaurant.
a. (ℎ) = (8.5 + 25)ℎ; $417.08
b. (ℎ) = 8.5ℎ + 25; $130.83
c. (ℎ) = 25ℎ + 8.5; $327.25
d. (ℎ) = 8.5ℎ + 25; $133.38

1st job $8.50 per hour

if h hours is worked per week in the restaurant, hence the total amount in the restaurant

= 8.5*h = 8.5h

For cleaning the house once a week to earn $25

Total from the two jobs = (8.5h + 25)

(h) = (8.5h + 25)

if 12 hours and 45 minutes was scheduled for the week.

h =12 hours 45 minutes;         45 minutes = 3/4 hour = 0.75 hour

h =12 hours 45 minutes = 12 + 0.75 = 12.75  hours. 

(h) = (8.5h + 25)            h = 12.75

(h) = (8.5*12.75 + 25)

(h) = (8.5*12.75 + 25) = 108.375 + 25 = 133.375 ≈ $133.38

So the answer is option

d. (ℎ) = 8.5ℎ + 25; $133.38

Hope this explains it.
