He saved up 64 dollars before he bought the game. First, you divide the video game cost by the amount of money he had spent(48/3). Your answer should be 16 dollars. Then, multiply by four because it is equal to the total amount of money(16*4). Your final answer should be 64 dollars.

Answer:
y = -3
Step-by-step explanation:
1.5y + 3 = -1.5
When doing algebraic equations, you are always doing PEMDAS backwards.
First, subtract:
1.5y = -4.5
Then divide:
y = -3
For 1 play, the chance of gaining $8 is 4/38, while the chance of losing the $1 is 34/38. Therefore, the expected value is ($8)(4/38) + ($-1)(34/38) = $(-1/19). Over 50 plays, which are mutually independent of each other, we multiply the number of plays by the expected value to get $(-50/19) = $-2.63.
