Answer:

Step-by-step explanation:

Let the student tickets sold = x

Let the non-student tickets = y

x + y = 311

0.5x + 1.5y  =  385.5       Multiply the second equation by 2

x + 3y = 771                      Subtract2y the first equation

<u>x +  y =  311</u>

     2y =460

      y = 230

x then will equal 311 - 230 = 81

Check

81 * 0.5 =       40.5

<u>230 * 1.5  =  345</u>

Total         = 385.5 just as it should

A new car is purchased for $49,000 and over time its value depreciates by one half every 5 years. What is the value of the car 2
vovikov84 [41]

Principal: $49,000

Depreciation Rate: 50%

Depreciation Time: 5 years

Exponential Function: y = 49,000 (0.50)^x

Plug it in: y = 49,000 (0.50)^4

0.5^4= 0.0625

0.0625 x 49,000 = 3062.5

Value of Car after 20 years: 3062.5

Now, we need to find out how much the car decreases in ONE year.

Half of 3062.5 = 1531.25

1531.25/5 = 306.25

3062.5 - 306.25 = 2756.25

Value of car after 21 years: $2756 ---> 2800 (nearest hundred dollars my bad)

Hope this helps! Have a great day!
