Astate offers two lottery games, winone and playball. both games cost $2 per ticket.

in winone, the player picks a single letter from a to j and a single digit from 0 to 9. if both the letter and the digit match the letter and the digit picked on that day, the player wins $150.
in playball, the player picks a single letter from a to t and a single digit from 0 to 9. if both the letter and the digit match the letter and the digit picked on that day, the player wins $280.

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

A. $1

Step-by-step explanation:

If he played WinOne 100 times, it means that he spent $200. If he won the lottery twice it means that he won $300 in total. We know that the earnings is given by the difference between the money won and the money spent.

Earnings = Won - Spent

Earnings $100.

Now, the net winning per turn is given by the division between the earnings and the number of times played:

Net winning per turn = $100/100 = $1

Therefore, he net winning per turn is $1.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
