Question

A group of 202 people went on an overnight camping trip, taking 60 tents with them. Some of the tents held 2 people each, and the rest held 4 people each. Assuming all the tents were filled to capacity and every person got to sleep in a tent, exactly how many of the tents were 2-person tents?

Answer 1

19

Explanation:

Answer 2

x = 2 person tents......y = 4 person tents

x + y = 60........y = 60 - x
2x + 4y = 202

2x + 4(60 - x) = 202
2x + 240 - 4x = 202
2x - 4x = 202 - 240
-2x = -38
x = -38/-2
x = 19 <== u have 19 two person tents

x + y = 60
19 + y = 60
y = 60 - 19
y = 41.....and 41 four person tents
