User: On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and children went?
Which of the following equations could not be used to solve the problem?
50x + 25(30 - x) = 1225
50(30 - x) + 25x = 1225
25x + 50x = 30(1225)

Weegy: The last equation could not be used. wheels926w|Points 10|

User: Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has $3.40 in all, how many nickels, dimes, and quarters does she have?
If n represents the number of nickels Janet has, which of the following equations could be used to solve the problem?
5n + 10n + 25n = 340
n + 3n + 2n = 340
5n + 30n + 50n = 340
