Question 1124083: Hi, I have a word problem I need help answering.
The cost of a 300 minute calling card is 15.00$.
A) what is the charge per minute? How do you know ? (I think it’s 20cents per minute because I divided 300 into 15.00, but I’m not sure)
B) using this card, what is the cost of a 20 minute call? What is the remaining value of the calling card after 20 minutes are used ?
