If Mr. Boyle played WinOne lottery 100 times and won twice, what were his net winnings per turn?
A: $1
B: $2.5
C:$3
D: $4

Respuesta :

Mr Boyle spends 2 * 100 = $200 in playing 100 games 
His winning come to 2*150 = $300 
so net winning = $100 
winnings per turn = 100 / 100 = $1

Answer:

Option A: $1

Step-by-step explanation:

Mr. Boyle played WinOne lottery game = 100 times

He spent on tickets = 100 × $2.00 = $200

Prize money for WinOne game = $150.00

He won 2 times and got prize = $150.00 × 2 = $300.00

His net winning prize would be = 300 - 200 = $100.00

Mr. Boyle's net winning per turn is = 100 / 100 = $1.00

Option A : $1 is the correct answer.
