x = # $5 unit you earn
2x = amount you save per unit
2x/4 = amount from parents
2x + 2x/4 = 40
10x/4 = 40
10x=160
x = 16 $5 units = $80 (oops....corrected 16 x5 = 80 not 75 as I originally posted)
m = 450
y = -3
Acceleration = change in velocity/change in time
= (vf - vo) / time
a = (2.8 -5.3) m/s / (.3 sec) = - 8.333 m/s^2

FV = PV(1+ int/2)^(yr*2) interest = YEARLY interest Divided by two to find interest per PERIOD (twice per year)
yr*2 = number of periods = # years * 2 times per year
FV = future value PV = present value (or initial deposit)
