LO = MN because LMNO is the isosceles trapezod
so <LON = <ONM = 100
Answer
<LON = 100 degrees
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
Lawns = L
Money he gets from mowing = M
M - $7 - (L * $1.50) = P for 1 Week
Hope this helped :D
