Suppose you are going into business mowing lawns. you
have purchased a lawn mower for $200. gas and oil costs
you $1.50 per lawn. you are charging $15 per lawn. how
many lawns must you mow to break even?

15 lawns

Step-by-step explanation:

Let

x ----> the number of lawns

y ----> the profit mowing lawns

we know that

The profit is equal to the revenue minus the costs

so

Break even means that the revenue is equal to the cost (profit is equal to zero)

so

For y=0

Round up

15 lawns

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
