Consider this option:
C³₂₇=27!/(3!*24!)=25*13*9=2925 ways to select 3 students.
<span>88 stamps -------------------- > $15.56
A------------------------------>number of </span>stamps ------------ ><span>25 cent
B----------------------------- > </span>number of stamps ------------ >2 cent
A+B=88------------------ > A=88-B
0.25A+.02B=15.56
resolving
0.25(88-B)+0.02B=15.56
22-0.25B+0.02B=15.56
-0.23B=-6.44----------------------- > B=28 stamps of 2 cent
A=88-B-- >88-28=60------------- > A=60 stamps of 25 cent
Just divide $40.68 by 3 and get $13.56
Answer:
4
Step-by-step explanation:
We know the other side of the rectangle is 18.
So 18=10+2x
subtract 10
8=2x
divide by 2
x=4
Wouldn't it be 140 bags with one of each in it; unless you need to use all the candies?
