Question

Margaret wants to call her friend overseas. There is a connection fee of $2 and a charge of $1.50 per minute. So the cost of the call is 2 + 1.5t dollars for t minutes.Can she talk for 15 minutes without going over a budget of $25?

Answer 1

Okay so 2$ + (1.5$x15m) = ?
2$ + ( 22.50$) = 24.50$
So yes she can talk for 15m and still stay under 25$

Answer 2

Yes, if she talks for 15 minutes, then that would equal 15×1.5, which is $22.50. If we add the connection fee of $2, then the total paid would be $24.50, meaning Margaret can talk for 15 minutes without going over a budget of $25.
