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
