Billy started a lawn mowing business and had to take out a $650 loan to buy all the supplies. The first month he made a profit of $600 and then the next two months he records a profit of $-75, and the last two months he made a profit each month of $150. What is the total profit of Billy’s business so far?

25

Step-by-step explanation:

He's already out of 50 bucks, because he didn't profit enough for his loan. So now we have -50, then in the next 2 months he records a profit of -75. We add that onto -50, to make -125. Then he makes 150 in profit so that's good good job Billy, -125+150=25. I hope this is right LOL

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
