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.

Answer:
6.6% = tax rate
Step-by-step explanation:
The first step is to find out how much was paid in tax
24.91 - 23.37 =1.54
The tax is 1.54
The tax is the original price * tax rate
1.54 = 23.37 * tax rate
Divide each side by 23.37
1.54/23.37 = tax rate
.065896448= tax rate
Changing to percent form
6.6% = tax rate
Answer:
Step-by-step explanation:If you choose any 3 of the 7 vertices, you can connect them with lines to create a unique triangle.
So, the question becomes "In how many different ways can we select 3 vertices from 7 vertices?"
Since the order in which we select the 3 vertices does not matter, we can use COMBINATIONS.
We can select 3 vertices from 7 vertices in 7C3 ways.
