Question Correction

Let A and B be two finite set such that n(A) = 20 , n(B) = 28 and n(AUB)=35, Find

Step-by-step explanation:

Given two finite sets such that:

We are to determine .

Now, by set theory

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
