We must divide the total height by the size of the blocks to work out how many are in the tower
22.5 / 1.5 = 15 blocks
That would be <span>50.6, I believe. You multiply 92 by 55% or .55 and get 50.6 </span>
C is your answer. Because 8 times 1.75$ = $14.00 and 5 times 1.25= $6.25. So $14.00+ $6.25 = $20.25
I would say that the answer is D 21.63
