Question

Please oh please help!!!

Admission to the zoo is $6 for children and $9 for adults. On a certain day, 1480 people go to the zoo and $10,500 is collected. How many children and how many adults went to the zoo?

______ Children
______ Adults

Answer 1

6x+9y = 10500
x+y = 1480

Using elimination I get:

6x + 9y = 10500
-6x-6y = -8880

Add the 2 equations and I get 3y = 1620

Divide both sides by 3 and I get y = 540

Substitute that back in to 6x+9y = 10500.

I get that 6x+9*540 = 10500

9 * 540 = 4860

Subtract 4860 from both sides and I get 6x = 5640

Divide both sides by 6 and I get x = 940

So there must have be 940 children and 540 adults
