Margaret wants to call her friend overseas. There is a connection fee of $3 and a charge of $1.40 per minute. So the cost of the call is 3+1.4t dollars for t minutes. Can she talk for 15 minutes without going over a budget of $25?

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.
