Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that x + y = 57, and since we want the number of children y, x = 57 - y

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

22x + 10y = 774

Since x = 57 - y

22(57 - y) + 10y = 774

1254 - 22y + 10y = 774

12y = 480

y = \frac{480}{12}

y = 40

40 children went on the cruise.
