Find the minimum number of prizes that can be distributed from , where the prizes are powers of 2.
STEP 1
Assumptions1. The prizes are powers of.
. The total amount to be distributed is $800.
3. We need to find the minimum number of prizes that can be distributed.
STEP 2
First, we need to understand that the powers of2 are1,2,4,8,16,32,64,128,256,512,1024, and so on.
STEP 3
We need to find the largest power of2 that is less than or equal to 512.
STEP 4
Subtract the largest power of2 from the total amount to find the remaining amount.
STEP 5
Plug in the values for the total amount and the largest power of2 to calculate the remaining amount.
STEP 6
Calculate the remaining amount.
STEP 7
Now, repeat the process with the remaining amount. Find the largest power of2 that is less than or equal to 256.
STEP 8
Subtract the largest power of2 from the remaining amount to find the new remaining amount.
STEP 9
Plug in the values for the remaining amount and the largest power of2 to calculate the new remaining amount.
STEP 10
Calculate the new remaining amount.
STEP 11
Now, notice that the new remaining amount is a power of. So, we can distribute this as a prize.
STEP 12
Count the number of prizes we have distributed. We have distributed one prize of 256, and one prize of $32. So, the minimum number of prizes that can be distributed is.
The minimum number of prizes that could be distributed from $800 is.
