She spent $65.
Step by Step-
She spent $15 on 3 blouses, so you would multiply and get that she spent $45 on blouses.
You would then add that to the $20 she spent before, and get $65.
Therefore, she spent $65.
Hope this helps!!
Let x = # of original members
Cost per person (originally) = 832/x
Cost per person after 6 more people = 832/(x+6)
Solve 832/x=832/(x+6) +6 (because the cost was reduced by 6
Solve for x.
x = 26 or -32 (but x is number of members, so it can't be negative)
# of original members is 26.
Original cost is 832/26 = $32 per person.
33/84 in simplest form is 11/28 because you can divide top and bottom by three. Just show that you divided both numbers by three and then you will get 11/28.
