<u>The second laptop</u>
- Initial value- $1200
- Value loss - 11% every year
- Function- V(t) = 1200*0.89^t

You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.
Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1
10x = 60 Divide by 10
x = 60/10
x = 6
Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10 = Final Result
60 * 1 / 10 = Final Result
Final Result = 6
This method words even when the numbers are quite complicated.
Answer:
<u>36.625</u>
Step-by-step explanation:
5*5 = 25
25 + 8 = 33
33 - 11 = 22
22 + 12 = 34
84/32 = 2.625
34 + 2.625 = 36.625
<u>36.625</u>
Have a nice day!
