The equation for direct-dial call is:
t = time in minutes for call
c = cost of call
c+=+.39+%2B+.25%2A%28t+-+1%29
given:
t+=+10
An operator assisted call to another country costs $5.84
for 10 min
------------
c+=+.39+%2B+.25%2A%28t+-+1%29
c+=+.39+%2B+.25%2A%2810+-+1%29
c+=+.39+%2B+2.5+-+.25
c+=+.39+%2B+2.25
c+=+2.64
5.84+-+2.64+=+3.20
The savings is $3.20
