This is a probablity question

there are 3 slots, 26 letters of the alphabet

so in the first slot, we have 26 possible letters
2nd slot, we have 25 possible letters (we used one for the first slot)
3rd slot, we have 24 possible letters, (we used 2 for first and 2nd slot)

so in total, we have 26*25*24 or 15600 different 3 letter initials with no repeated letters

Answer:

5 Soup can

Step-by-step explanation:

If 3 soup can cost $3.75

Then 1 soup can will cost $3.75/3

So, how many can soup will cost $6.25

= $6.26/(cost of 1 soup can)

= $6.25/($3.75/3)

=$6.25 × 3÷ 3.75

= 5 cans of soup

140 fluid ounces increased by 45%
Stels [109]
Hello!

"Increase" means to add. We must find out what 45% of 140 fluid ounces is, and to do that we must first convert the percentage to a decimal and then multiply it by the amount of fluid ounces.

I know, that's probably a lot to take in! :D

45% ÷ 100 = 0.45 as a decimal

0.45 × 140 = 63

Add this to the amount of fluid ounces:

140 + 63 = 203

Final Answer:

203 fluid ounces.
