Answer:
{{{system(
x+y = 1500888647,
y = x+366593903
)}}}
x = number of $2 bills
y = number of $50 bills



Explanation:
The expression x+y is the total of number of $2 or $50 bills. This total is set equal to the 1,500,888,647 (roughly 1.5 billion) mentioned. This is how the first equation was set up.
