I'm guessing I need to use y=mx + c but i'm not sure how to do that on excel.

"

A builder has a plot of land available on which he can build either luxury of standard houses.

He decides to build at least 5 luxury and 10 standard houses. Planning restrictions limit him

to no more than 30 houses altogether. A luxury house requires 300m2

of land and a standard

house 150m2

. The plot is 6000m2

. Profit is $12; 000 per luxury house and $8000 per standard

house. How many of each type should he build to maximise his profit."

Thank you anyone that can help!
