Answer: 91. I find the easiest method for questions like this about ratios is to multiply the side of the ratio you are given a value for, in this case the right hand side (children), by a number so it equals the value given. This was 2x13 to equal 26. Then, to find the value of the other side, the adults, you must multiply the left hand side by the same number used on the right hand side. 7x13 equals 91.

Answer:
The value of the car will be $2,363.19 after 14 years
Step-by-step explanation:
The rule of depreciating is
, where
- <em>A</em> is the new value
- <em>P</em> is the original value
- <em>r</em> is the rate in decimal
- <em>t</em> is the time in years
∵ A new car is purchased for 18000 dollars
∴ <em>P</em> = 18,000
∵ It depreciates at a rate of 13.5% per year
∴ <em>r </em>= 13.5% = 13.5/100 = 0.135
∵ We need to find how much it will be worth after 14 years
∴ <em>t</em> = 14
→ Substitute all of these values in the rule above to find <em>A</em>
∵ 
→ Use your calculator to find the answer
∴ <em>A</em> = 2,363.186569
→ Round it to the nearest cent (2d.p.)
∴ <em>A</em> = 2,363.19
∴ The value of the car will be $2,363.19 after 14 years.
