It takes 40 minutes for 8 people to paint 4 walls.

How many minutes does it take 10 people to paint 7 walls?

4*10 = 40

7:4 walls = 10:8 people =M:40 minutes

M = (7/4) / (10/8) x 40

M = 56 minutes.

The population of Bakersville is 145,712.  35% of the population is very rich and wealthy, 50% are from middle-class families, and the rest of the population is homeless. Change the percentages into the number of people in each of the listed groups.

145,712 x 0.35 =50,999 people that are very rich and wealthy.

145,712 x o.50 =72,856 people that are middle-class.

145,712 - [50,999 + 72,856] =21,857 people that are homeless, which is 15% of the city population!![I hope this is not true!!].

35Γ(-67) - 9.7Γ5/12Γ(-22)

-2,345 - 48.5/12 x (-22)

-2,345 + 1,067/12

-2,345 + 88.916667.......

= -2,256.0833..........
