Answer:
V=129659.9491≈129659.95
Step-by-step explanation:
If a bagel costs $0.80 any day, then the unit price
is $0.80 per bagel.
If the unit price of a bagel is $0.80 , then every bagel
you buy costs $0.80 .
Only one thing changes: The price of a dozen on Wednesday.
If you buy 1 dozen ... or any number of dozens ... on Wednesday,
then the unit price of the contents of that bag is
($6.00) / (1 dozen) = $6.00 per dozen
If you want to convert that to a
different unit of measure, then
you do it like this:
(6.00 $/dozen) x (1 dozen/12 bagels)
= (6.00 x 1 / 12) ($/bagel)
= 0.5 $/bagel
or $0.50 / bagel .
Simply make the line, and then add the units equally.

Answer: 9/100</h3>
========================================================
Explanation:
There are 3 pink marbles out of 10 total (we can see that 2 yellow + 3 pink + 5 blue = 10 total)
The fraction 3/10 represents the probability of pulling out a pink marble at random. Since the first one is put back, this means the fraction 3/10 stays the same on the second draw as well.
We use the idea mentioned in the hint to multiply the fractions:
(3/10)*(3/10) = (3*3)/(10*10) = 9/100
The probability of pulling two pink marbles in a row is 9/100, where the first marble is put back.
Effectively, if you were given 100 tries at doing this, you should expect about 9 of those times you get 2 pink marbles in a row.
