y = 55x+85 

where x = 1 hour 

insert x = 1 into the equation 

y = 55(1)+85

hey @MysticFury that equation doesn't match the data table

mysticfury · Answer

yes i know, because the table is what the electrician charges, not the plumber... no one seems to understand that lol

mysticfury · Answer

your supposed to use the table to figure out the electricians hourly rate

photon336 · Answer

plumber charges 140 we know that already now let's find the electrician's hourly rate

mysticfury · Answer

well if you did it that way it would be simple, plumber would charge 140, and electrician would charge 115, but wait that dosent add up, since 115 + 115 isnt 180

photon336 · Answer

y = 55x+85  plumber 

y = 65x+50  electrician

mysticfury · Answer

thats what i got

photon336 · Answer

I agree with you.. it's just  the way I read this equation is 55 dollars par hour plus an additional 85 dollars.
