Question

Write the equation of the line that represents the following scenario:
You are starting a new lawn mowing business. It will cost you $50 to pay for supplies and then you will charge $25 for each time you mow a lawn.

A.	y = 25x + 50
	B.	y = 25x - 50
	C.	y = 50x - 25
	D.	y = 50 + 25

anonymous · Answer

A.

If you mow 0 lawns (x = 0) you still have to charge $50, so that eliminates B, C, and D as answer choices. As well, you need to charge $25 for each lawn mowed (x), so you just add 25x to 50, to get y = 25x + 50.
