. Write the exponential function modeling an initial population of 67,000 and a relative growth rate of 1.7% per year. What popu
Vlada [557]

Answer:

In 37 years the population will be 125,012

Step-by-step explanation:

Giving the following information:

Initial population (PV)= 67,000

Growth rate (g)= 1.7%= 0.017

Number of years (n)= 37

<u>First, we will establish the future value (FV) formula:</u>

FV= PV*(1+i)^n

FV= 67,000*(1.017^n)

<u>Now, for 37 years:</u>

FV= 67,000*(1.017^37)

FV= 125,012

In 37 years the population will be 125,012

Marc sold 516 tickets for the school play. Student tickets cost $3 and adult tickets cost $5. Marc's sales totaled $2046. How ma
mrs_skeptik [129]
Let student tickets are x and adult tickets are y

x + y = 516.........x = 516 - y .........(substitute in 2)

3x + 5y = 2046 ......(2)

3(516-y) + 5y = 2046

1548 - 3y + 5y = 2046

2y = 498

y = 249

x = 516 - y = 516 - 249 = 267

so the correct answer is b
