19. 9.29
20. 1.65
The exponential growth formula is as follows
$y=a(1+r)^{x}$ :
a is initial value
($27,225 17. gallon of gas, $1.08 18. dozen eggs, $0.89 19. movie admission, $3.50 20. mcdonalds hamburger, $0.62)
r is rate of increase (0.05)
x is time (2008-1988 = 20 years)
to solve plug in values for each one.
 $y=27225(1+0.05)^{20} = 72236.03$

$1.08(1+0.05)^{20} = 2.87$

$.89(1+0.05)^{20} = 2.36$

$3.50(1+0.05)^{20} = 9.29$

$.62(1+0.05)^{20} = 1.65$
