First we need to find 2% of 35,000
2% equals 0.02 so we'll multiply 35,000 by 0.02
35,000 × 0.02 = 700
for every car he sells jack gets $700
now we need to divide that into 5,000
5,000 ÷ 700 = 7.14
now since you cannot sell 0.14 of a car you need to round up
he needs to sell 8 cars to meet his target income
Answer:
Let b = rate of the boat.
Let r = rate of the river.
The rate going downstream is b + r.
The rate going upstream is b - r.
rate x time = distance
4(b + r) = 144 ---> b + r = 36 [divide both sides by 4]
9(b - r) = 144 ---> b - r = 16 [divide both sides by 9]
Add town: 2b = 52
Divide by : b = 26 mi/hr
r = 10 mi/hr
Step-by-step explanation:
The least common multiple of 9 and 21 is 63
Infinite intervals are closed if they contain a finite endpoint, and open otherwise. The entire real line is an infinite interval that is both open and closed
