Question 449961: a direct dialed telephone call from Tampa to new york is $3.05 for the first 3 minutes and .70 cents for each additional minute or fraction thereof. If Juan's call cost $7.95 how many minutes was the call?

You can put this solution on YOUR website!
Let +n+ = number of minutes of the call
+795+=+305+%2B+.7%28n+-+3%29+ (in cents)
+795+=+305+%2B+.7n+-+2.1+
+.7n+=+795+-+305+%2B+2.1+
+.7n+=+492.1+
+n+=+703+
This is too much- should .70 cents be 70 cents ?
