33/4 is the same as 8 1/4
so that means that matt bought the Volvo for 8 1/4 times as much as the car his parents bought.

Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
First, get the difference between the price level changes.
Then, divide it by the initial price level, which is 109.
Multiply by 100 to get its percent.
Thefore, the inflation rate during the year is 3.67 percent.
The speed is 630mp/s I think. Because you have to multiply Wavelength by Frequency to get true speed
