Answer:
7

Multiply it with 8 to get 7
.875*8=7
Well, due to that 10% of the muffins get wasted and do not sell,
plus work that goes into it, the price of the ice-cream is not 0.60,
but 55% more, or markup above that cost value
so... how much would each muffin sell for? well, each muffin will be,
0.60 + 55% of 0.60
how much is 55% of 0.60?
get the 55%, and add it to the 0.60, that's how much each will sell for
Well, the problem is that he does not replace the first marble after he draws it. Therefore, yes, he has a 2/12 probability of drawing a yellow marble first, but then he has a 4/11 probability of drawing a red marble second, not 4/12. This is because there are going to only be 11 marbles left in the bag after he draws the first marble and does not replace it.
The correct answer would be:
(2/12)(4/11)=8/132=4/66=2/33
40 + 30s = 220
30 for each student (s) and the one charge of 40 would get the tutor 220 dollars.
I believe it's the same as adding 8+3, but you add the negative sign to your answer
so 8+3 = (-?)
