Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Saturday, he works 5 hours and earns $42.50 On Sunday, he works 8 hours and earns $68,00 Which of the following functions models Angels savings?

The second choice is correct. (f(x) = 8.50x+7.50)

Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50  dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

Let me know if this helps!

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
