Answer:
$169803
Step-by-step explanation:
Given data
rate of decrease = 5.4%
time = 2009-2021= 12years
P= $331,000
Let us apply the compound interest formula
A=P(1-r)^t----------------note the minus sign because this is a decrease
A= 331000(1-0.054)^12
A= 331000(0.946)^12
A= 331000*0.513
A=$169803
Hence the value in 2021 is $169803
Answer:
A = -10*p + 2220
Step-by-step explanation:
To write a linear equation let define
A = attendance
m = slope of the line
b = intercept of the line
p = Price of admision
let´s find m, using the two points (p,A)
point 1 = (17, 2050)
point 2 = (12, 2100)
m = (2100 – 2050)/(12-17) = -10
Replacing m in the equation
A=-10p+b
To find b, let´s use point 1
2050 = -10*17 + b
B = 2050 + 170
b = 2220
finally, the equation is
A = -10*p + 2220
The answer to your question is B
