I bought a used car at 50%-off sale. I didn't drive it much, so I sold it for 50% more than I paid for it. When I missed having "wheels," I bought the car back at 50% less than I sold it for. Soon gas was costing too much, so I sold the car again for 50% more than I paid for it the second time. Now I am confused, so I hope you can help. What percent of my original investment did I make or lose?

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
