Let the cost of petrol of the car be £ x
£x=580mile
33.5mile=1gallon
1gallon=4.55litre
1litre=£1.09
By using chain rule,
X x33.5x1x1=580x1x4.55x1.09
Or,x=85.86
So x=£85.86

Answer:
The amount Tobie invests in a bank, P = $25
The annual compound interest rate, i = 4%
a. The principal is amount invested in the bank, P = $25
The annual interest rate, i = 4%
b. The function that represents Tobie's account balance, <em>A</em>, after <em>t</em> years is given as follows;

Where;
A(t) = The amount in the account after <em>t</em> years
P = The principal amount
i = The annual compound interest rate
t = The number of years
c. The values to place in the table are found as follows;
At t = 0,
= 25
At t = 10,
= 37
The given table is presented as follows;

Step-by-step explanation:
Since the sum of two numbers is 67
and one number is p
so the other number is (67-p)
