Lisa wants to buy a phone card for $5. company x charges $0.49 for the first minute and $0.16 for each additional minute. company y charges $0.57 for the first minute and $0.12 for each additional minute. if lisa makes just one call, which phone company gives her more minutes for $5? how many more minutes?

So for $5, let's calculate each company's minutes for that much money.

Company X: First subtract the time for the first minute.

5 - 0.49 = 4.51

Then divide by 0.16, and you get about 28 minutes.

28 + the original 1 minute = 29 minutes

Company Y: $5 - 0.57 = 4.43

4.43 / 0.12 = about 36 + the original one minute = 37 minutes

So Company Y gives her more minutes for 5 dollars, and also 8 more.
