Answer:
46.25% is the percent of the change in the price of a cell phone from 2000 to today.
Step-by-step explanation:
Cost of a cell phone in the year of 2000. C= $240
Cost of a same cell phone today, C'= $129
The percent of the change in price:
[tex]\frac{C-C'}{C}\times 100[/tex]:
[tex]\frac{\$240-\$129}{\$240}\times 100=46.25\%[/tex]
46.25% is the percentage of the change in the price of a cell phone from 2000 to today.
