Today the price of a new cell phone is $129 in 2000 the price of a similar cell phone was $240 what is the percent of the change

netineya [11]

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.

A movie theater has been charging $10.00 per person and selling about 500 tickets on a typical weeknight. After surveying their

kifflom [539]

Answer:

$p(x) = -0.01x + 15$

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

$(x_1,p_1) = (500,10)$

A reduction of 50c gives an increment of 50 tickets.

This gives:

$(x_2,p_2) = (500+50,10-0,5)$ ---- $50c = \$0.5$

$(x_2,p_2) = (550,9.5)$

Required

Determine the demand function

First, calculate the slope:

$m = \frac{p_2 - p_1}{x_2 - x_1}$

$m = \frac{9.5 - 10}{550-500}$

$m = \frac{-0.5}{50}$

$m = -0.01$

So, the equation is:

$p = m(x - x_1) + y_1$

$p = -0.01(x - 500) +10$

$p = -0.01x + 5 +10$

$p = -0.01x + 15$

Hence, the function is:

$p(x) = -0.01x + 15$
