Answer:

Step-by-step explanation:

Given the following :

Period = 15 years

Worth of investment = $7,200

The rule of 70 is represented by the formular :

Number of years to double = ( 70 / Annual percentage growth rate)

Inputting our values :

Number of years to double = 15 years

15 = 70 / Annual percentage growth rate

Annual percentage growth rate * 15 = 70

Annual percentage growth rate = (70 / 15)

= 4.667%

Therefore according to the rule of 70, it will take an annual percentage growth rate of 4.667% to double the investment.

a) The cost for 10 mile taxi ride is $18

b) The cost for m mile taxi ride is 1.5 m + 3

Step-by-step explanation:

Step 1 :

The fixed charges for the pick up = $3

Charges per mile = $1.50

Let s denote the total miles driven and t be the total cost for the trip

This can be represented by the equation

t = 3 + 1.5s

Step 2:

Distance traveled by Jonathan in his trip = 10 miles

So cost for riding 10 miles is

t = 3 + 1.5(10) = 3 + 15 = $18

The cost for 10 mile taxi ride is $18

Step 3 :

If the distance traveled is m miles, then substituting s = m in the above equation we get the cost as 1.5 m + 3

Step 4 :

Answer :

a) The cost for 10 mile taxi ride is $18

b) The cost for m mile taxi ride is 1.5 m + 3
