Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160 -160
0 5x = 340
divide both sides by 5
5x/5 = 340/5
x = 68
so they need to sell 68 tickets at the door.
4(40) + 5(68) = 400
160 + 340 + 400
400 + 400
3.142 because if you put pi in a calculator, it will be 3.1425..., ad 3.142 is closer to 3.1425 than 3.141
1. controle if no numbers are missing and the numbers are in the right order
2. the formula is x-a so a=1
3. write everything out in the scheme
4. let the first number drop down
5. multiply the answers by a
6. add the number that are under each other
7. repeat 5 and 6 until to you're done
8. write down the equation
9. last number in the scheme is your residue, which means that you write it at the end, outside of the ()
The answer for this question is 26
Number of members = 13
Total investment = $24,689.55
Since they have equal shares, dividing the total investment with number of members gives shares value per member.
