Question

There were 490 people at play. The admission price was $3.00 for adults and $1.00 for children. The admission receipts were $990. How many adults and children attended

Answer 1

Hope this helps! This is system of equations.

Answer 2

A + c = 490....a = 490 - c
3a + c = 990

3(490 - c) + c = 990
1470 - 3c + c = 990
-3c + c = 990 - 1470
-2c = - 480
c = -480 / -2
c = 240 <=== there were 240 children

a + c = 490
a + 240 = 490
a = 490 - 240
a = 250 <== there were 250 adults
