Answer: There were 7 children
Step-by-step explanation:
Let's use <em>x </em>to represent the children and <em>y </em>to represent the adults.

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201
I will solve by substitution.
Solve for y in the first equation
Sub in our value for y into the other equation and solve for x
Step 1) Simplify
Step 2) Subtract 250 from both sides
Step 3) Divide both sides by -7
