Answer: 15%
Step-by-step explanation:
Given: The original value of car : [tex]\$5,200[/tex]
The value of car after one year : [tex]\$4,420[/tex]
Now, the percent of decrease in the value of her car is given by :-
[tex]\dfrac{\text{Change in price}}{\text{Original price}}\times100\\\\\\=\dfrac{5200-4420}{5200}\times100=15\%[/tex]
Hence, the percent of decrease in the value of her car = 15%
