Answer 1

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:

$\frac{C-C'}{C}\times 100$:

$\frac{\ 240-\ 129}{\ 240}\times 100=46.25\%$

46.25% is the percentage of the change in the price of a cell phone from 2000 to today.
