A+a+3=a+13
2a+3=a+13
From here you want the variables on the same side, so you would subtract the a from a+13 and move it to 2a+3
2a+3=a+13
-a -a
a+3=13
Now you want the numbers on the same side
a+3=13
-3 -3
a=10
18/38 - 47% chance of success
$1 to $100 - $10 to spend
With this given information, their is two routes to take, play it safe, or defy the odds. Though, a 47% chance isn’t far from 50/50, and at the end of the day, it is only $10 to lose. Therefore, in my opinion, even with the expected value, I would say to bet all the money at once, since the goal is to leave with $20.

10 x 4
Step-by-step explanation:

10 plus 10 and 4 plus 4 equals 28. 4 x 10 equals 40.
2 is the correct answer I believe
