Question

Sally invests $300 in a lawn mowing business to buy a mower and other supplies. She charges $20 for each lawn she mows. Write an equation to show the amount of money she has earned (y), for any number of lawns mowed (x).
y=20x-300
y=20x+3000
y=300x+20
20x+300y=230

Answer 1

is this supposed to be multiple choice or hwy do you have 4 lines?

Answer 2

multiple choice

Answer 3

which one would you pick out of these options?

Answer 4

idk

Answer 5

well, to know how much Sally earned, you have to start from -300, because that's her initial investment.

Then for every lawn you add 20.

Answer 6

so the part +20x means for every lawn, $20 is added to the profit.

Answer 7

and the -300 does not really change, as no extra investments are necessary, at least none are mentioned in the exercise.

Answer 8

.y=20x-300

Answer 9

yes
