(a)age=14
(h)hieght=67"
Solve the formula for age(a). Estimate how old you will be when your air volume is 90% of its current volume.
(use current height)
solve the formula for a:
V=0.104h-0.018a-2.69
V+2.69=0.104h-0.018a
V+2.69-0.104h=-0.018a
----------------------------------------------
Solve for V so you can plug 90% of it in later...
V at a=14 and h=67:
V=0.104h-0.018a-2.69
V=0.104(67)-0.018(14)-2.69
V=4.026
----------------------------------------------
a for h=67 and .9V when V=4.026--------->90% of V
V=0.104h-0.018a-2.69
.9V=(0.104h-0.018a-2.69)
.9(4.026)=(0.104(67)-0.018a-2.69)
3.6234=6.968-.018a-2.69)
3.6234=4.278-.018a
-.6546=-.018a
36.4=a
