Oh and on number 4 letter D, I meant to put 10% off, and not of!
This is a very strange bank. Using the formula I=Prt. we have
275*0.045*5 = 61.875 on the 1st year's deposit
275*0.045*4 = 49.5 on the 2nd deposit
and so on, giving
275*0.045*(5+4+3+2+1) = 275*0.045*15 = 185.625 total interest
Just compare the prices.
(A) 15+12*0.79
(B) 17+12*0.69
(C) 24.99-3.00
(D) 22.50 * 0.90
275*0.045*5 = 61.875 on the 1st year's deposit
275*0.045*4 = 49.5 on the 2nd deposit
and so on, giving
275*0.045*(5+4+3+2+1) = 275*0.045*15 = 185.625 total interest
Just compare the prices.
(A) 15+12*0.79
(B) 17+12*0.69
(C) 24.99-3.00
(D) 22.50 * 0.90

3D is correct
4. but the best buy is usually considered to be the one with the lowest price, right?
Now go read Bartholomew and the Oobleck by Dr. Seuss.
