Question

Andrew is paid 4$ per hour for the first 30 hours he works each week. He makes 5$ per hour for each hour he works over 30 hours per week. In other words, total wages=fixed wages for 30 hours + additional wages at 5$ per hour. Write a function that gives Andrews total wages when he works more than 30 hours

Answer 1

Because the first wage is determined, here's the start of our sentence:
4(30)
Now, we know that any number above thirty turns into $5 an hour, so:
4(30) + 5(h - 30)
h represents hours, but because he only gets 5 an hour for his work above 30 hours, we must subtract five from the sentence.
So the function:
f(h) = 4(30) + 5(h - 30)
Or, simpler:
f(h) = 5h - 30

Answer 2

f(x)= 4 + 5x

this is like a linear equation but you replace y with f of x

4 is the money he make the first 30 hrs and the 5 is the 5 dollars and x is the number of hours
