Final answer:

Margaret can talk for 15 minutes without going over her budget of $25.

Step-by-step explanation:

To determine if Margaret can talk for 15 minutes without going over her budget of $25, we need to calculate the cost of the call for 15 minutes. The cost of the call is $3 for the connection fee plus $1.40 per minute. So for 15 minutes, the cost would be $3 + ($1.40 x 15) = $3 + $21 = $24. Therefore, Margaret can talk for 15 minutes without going over budget.

Answer:

yes she can

Step-by-step explanation:

y = 1.4(t) + 3

y = 1.4(15) + 3

y = 21 + 3

y = 24

since the total is 24, which is less than 25, she can talk for 15 minutes.
