Step-by-step explanation:
A. Personally if i was given these 2 options i would take the choice of drawing 2 bills from the bag per week.
B. Yes, i do not think pulling 2 bills from the bag is a good way to make money.
A. You could either get 10$ per week or you could get, 2$ 6$ 6$ 10$ 11$ 11$ 15$ 15$ now this depends largely on luck but logically 5 out of 9 times you will get 10 dollars or more so there is a higher chance you get more money from drawing money.
B. It is a good way to make money because 2/9ths of the time you will get 15$ and for every time you get 6$ you will get an equal amount of 15$ and you will get 21$ in the 2 weeks so it adds up, if you have bad luck or do this for a short amount of time then you could be losing out but if you have an average amount of luck then it will be worth the chance.

Answer:
(x, y) = (3, 1)
Step-by-step explanation:
given the 2 equations
2x + 3y = 9 → (1)
x + 5y = 8 → (2)
multiplying (2) by - 2 then adding to (1) will eliminate the term in x
multiply (2) by - 2
- 2x - 10y = - 16 → (3)
add 1(1) and (3) term by term
(2x - 2x) + (3y - 10y) = (9 - 16)
- 7y = - 7 ( divide both sides by - 7 )
y = 1
Substitute y = 1 in either (1) or (2) and solve for x
(1) : 2x + 3 = 9 ( subtract 3 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Solution is (3, 1 )
