The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
Answer:
Step-by-step explanation:
Cost Price = Rs. 400
Profit = 4 % of Cost Price
=> 
=> 4 * 6
=> Profit = Rs. 24
Now, Selling Price = Cost Price + Profit
Selling Price = 400+24
Selling Price = Rs. 424
There are two coefficients in this equatin,why because we have two variables "x and y " . Therefore the coefficients are (+6 for variable x) and (+14 for variable y) and we have only one constant...why? because we can only have one constant in a given equation.
400$
Explanation:
In 1992, the price is 28000$ and 9600$ in 1996 so in 4 years the value the car lost is 18400$
Dividing 18400 by 4 years we get 4600 depreciation value per year.
Between 1996 and 1998 there is 2 years
So in 1998 the value of the car will be:
9600 (value in 1996) - 2x4600 = 400$
4(-8+4.5)
-32+18
-14
6.25+(-8.25)
-2
-14/-2
7
The answer is 7.
