Two cargo ship captains at lunch argue over who does better business. Mal says, “I make $10 for every package I ship, plus a $70 fee.” Han replies, “Well, I make 4 times that much!” Let R be the total revenue, and let x be the number of packages. If Mal and Han would stop fighting and work together, write an equation that shows how much money they would make as a function of x.

HI!!

OpenStudy (misty1212):

confused by this one as well? we can do it !

OpenStudy (misty1212):

first guy makes $70 flat fee plus $10 a package, so if he ships \(x\) packages he makes \[10x+70\] dollars

OpenStudy (misty1212):

since the other guy makes four times as much he makes \[4(10x+70)=40x+280\] dollars

OpenStudy (misty1212):

together you add them up \[10x+70+40x+280\]

OpenStudy (misty1212):

you got how to add those?
