4x + y = 5
3x + y = 8
y = -3x + 8
4x +(-3x + 8) = 5
4x -3x + 8 = 5
x + 8 = 5
x = -3
y = -3(-3) + 8
y = -9 + 8
y = -1

Answer:
p(0) = 800
p(8) = 997
Step-by-step explanation:
p(t) = 800 * (1.028)^t
The current price is when t=0
p(0) = 800 * (1.028)^0
= 800(1)
= 800
The price in 8 years
p(8) = 800 * (1.028)^8
=997.7802522414861936754688
To the nearest dollar
= 998
