Answer:
The expression below represents this situation.
d-0.09d
'd' is the original price of the car (also given Jessica purchased a car for d dollars a few years ago.)
And 0.09d means that 0.09 of 'd' was decreased from original price. This is 9%.
So, Jessica's car depreciated by 9% during this time period.
An equivalent expression that represents this situation is given by solving the equation.
Answer:
"Jessica's car depreciated by 9% during this time period. An equivalent expression that represents this situation is 0.91d "
Step-by-step explanation:
The original amount is "d"
and the next term "-0.09d" is the amount of depreciation with respect to d
0.09 * 100 = 9%
Hence, the depreciation rate is 9%
To find an equivalent expression, we simply add/subtract the like terms.
<em>e.g. 5x - 2x = (5-2)x = 3x</em>
So we have:
d - 0.09 d
1d - 0.09d
(1-0.09) d
0.91d
The equivalent expression is
