A telecommunications company offers two calling cards. The first card costs $25 for 750 minutes, while the second card costs $40 for 1,300 minutes. Which is the better deal? $ ? for ? minutes is the better deal.

Step-by-step explanation:

You can use the unituary method in this one

First card:

$25/750 min

divide both sides by 750 to figure out how many $ per min the calling card would be

25/750=0.033333333333333333333333333333333333333

750/750=1

the first card costs $0.03333333(going on)/min

Second card

$40/1,300 min

Divide both sides by 1,300

40/1300=0.03076923

1300/1300=1

Second card costs $0.03076923/min

$0.03076923<$0.03333333(going on)

therefore the second card is the better deal

you should add the points so we know what to choose from.   but to figure out the answer, graph it.   then any points the are on the line are solutions.
