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

q: 92 degrees

hope i ^-^

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
