Money Short

Number Theory Level 4

Four friends--let's call them A, B, C, and D--are planning to go to the concert, but they realize that they are a few dollars short to buy the tickets ($50 per ticket).

We know that each of them has an integer amount of dollars and that

if $B$ borrowed $ $1$ from $A$ , then $B$ would have $\frac{2}{3}$ of $A$ 's balance;
if $C$ borrowed $ $2$ from $B$ , then $C$ would have $\frac{3}{5}$ of $B$ 's balance;
if $D$ borrowed $ $3$ from $C$ , then $D$ would have $\frac{5}{7}$ of $C$ 's balance.

At least how much more money (in $) do they need all together in order to afford 4 tickets?
