3. Plumber-A charges $25 for a service call plus $50 per hour of service. Plumber-B charges $60 for a service call plus $40 per hour of service. For both scenarios, write an equation using
function notation for the cost after h hours of service. At what number of hours will both
plumbers cost the same? Which plumber is more affordable after 4 hours? Explain.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

$113.42

i hope that is right.

step-by-step explanation:

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
