On Saturday morning, Renata had $10 to spend. She first went and made a $4 donation in exchange for a ticket to the local charity draw. When the draw was done, she was declared the winner of the 5th prize of $90. Excited, she quickly dashed to play slots at one of the casinos in Atlantic City. Unfortunately, she lost $50 at the first slot machine, $10 at the second and $5 at the last one. Dejected, she decided to take a long walk. She soon grew thirsty and entered the first gas station she saw. She picked a $1 bottle of water and while paying for it, she bought a $1 lottery ticket. To her utter delight, she won an instant prize of $65. How much money did Renata end up having? Think carefully first, then make a decision:

After the charity ticket purchase on Saturday morning, Renata remained with 10 - 4 = 6 dollars. Adding the prize money give her 6 + 90 = 96 dollars. At the casino, she lost 50 + 10 + 5 = 65 dollars. Thus far, Renata remained with 96 - 65 = 31 dollars. The amount she spent on the bottle of water and lottery ticket is 1 + 1 = 2 dollars. This means that she remained with 31 - 2 = 29 dollars. Since she won 65 dollars, Renata’s ended up having 29 + 65 = 94 dollars. So, the answer is 94.
