If you mean 1/3 the answer is -15.5
1/3(-32.48-14.02) = 1/3(-46.5) = (-15.5)
The formula is
A=p (1+rt)
A future value
P present value
R interest rate
T time in years
Rose investment
A=2,600×(1+0.041×9)
A=3,559.4
Dennis investment
A=2,200×(1+0.057×9)
A=3,328.6
So Rose investment is greater than Dennis investment by
3,559.4−3,328.6=230.8
Hope it helps!
