Answer:
If PG = $7300, then PS = $8000
Step-by-step explanation:
You want the cost of the transfer in each direction to be the same, so ...
0.80PG = 0.73PS
PG/PS = 0.73/0.80 = 73/80
Expressed another way:
PG : PS = 73 : 80
Here, we have chosen to multiply these numbers by 100 to give the values PG = 7300 and PS = 8000 in order to achieve the desired ratio.
