Suppose a 15-minute call costs $5.26, and a 30-minute call costs $10.24. Find a formula relating time (in minutes) and cost (in dollars).
1 answer:
If 15 minutes is $5.26 then 1 minute is 35¢ so the equation is y=.35t. But 30 minutes is $10.24 so 1 minute would be 34¢ so the equation would be y=.34t.
