Problema Solution
There were 510 people at a play. The admission price was $2 for adults and $1 for children. The admission receipts were $810. How many adults and how many children attended?
Answer provided by our tutors
x = adults
y = children
x + y = 510
y = 510 - x
2x + y = 810
2x + 510 - x = 810
x = 300 adults
y = 510 - 300 = 210 children
