A rental car agency charges $160.00 per week $0.15 per mile to rent a car. how many miles can you travel in one week for $257.60

OleMash [197]

Answer:

Firstly Subtract the weekly charge from the total

257.60 - 160 = 97.6

So 97.6 was charged for miles travelled

Since we know one mile is for 0.15, we divide

97.6 ÷ 0.15 = 650.7

Therefore 650.7 miles were travelled.

The fish population is decreasing at a rate of 3% per year. In 2002 there were about 2100 fish. Find the fish population in 2010

djyliett [7]

Answer:

Population of fish in 2010 = 1,646 fish (Approx.)

Step-by-step explanation:

Given:

Population of fish in 2002 = 2100 fish

Decrease rate = 3% per year

Find:

Population of fish in 2010

Computation:

Number of year = 2010 - 2002

Number of year = 8 year

A = P[1+r]ⁿ

Population of fish in 2010 = Population of fish in 2002[1+(-3%)]ⁿ

Population of fish in 2010 = 2100[1-0.03]⁸

Population of fish in 2010 = 2100[0.97]⁸

Population of fish in 2010 = 2100[0.7837]

Population of fish in 2010 = 1645.77

Population of fish in 2010 = 1,646 fish (Approx.)
