PLEASE HELP ASAP
1. The amount of Kelly's paycheck varies directly with the number of hours
she works. Kelly receives $139.80 for 12 hours of work.
(a) Write a direct variation equation that relates the amount of Kelly's paycheck, y, to the number of hours, x,
that Kelly works.
(b) use the equation to find the amount of Kelly’s paycheck when she works 40 hours.

Answer:

(A) p=11.65h

(B) h=22

(C) p=466

Step-by-step explanation:

A) The equation for direct variation is usually y=kx, K being the constant variation, Y being the amount of Kelly’s paycheck, and x being the number of hours. So the equation would turn into p=kh. Then you have to plug in the numbers they gave you which would be, 139.80=12k. When you plug that into a calculator you get, K=11.65. So, the answer would be p=11.65h

B) For B we’re keeping the same format of the equation from question A which would be p=11.65h, but were plugging in p, the amount of paycheck she receives so, the 256.3 so our new equation would be 256.3=11.65h, putting that into a calculator will give you the answer which is h=22.

C) Same thing as question B we are keeping the same format of the equation as Question A but this time we’re pluggin in h, the amount of hours Kelly works. So our equation would be p=11.65(40). Plugging that into the calculator will give you p=466.

Hope this helps.
