Given that Carlene needs $500 for a desk, the time taken for her to purchase the desk will be found as follows;
500=400e^(0.06t)
500/400=e^(0.06t)
1.25=e^0.06t
introducing natural logs;
ln1.25=0.06t
t=(ln1.25)/0.06
t=3.7 years
the answer is 3.7 years

Louis is wrong as you do the things in the bracket first there for you would do this (5x3+3)2= (15+3)2= (18)2= 18x2 = 36
