TO answer this first we will see how many campers sleep in cabins. To do dis we will subtract d amount of total campers to d amount of oldest campers. lets do it:-
320 - 112 = 208
So we know there are 13 cabins. So lets work tat out:-
208 ÷ 13 = 16
16 capers per cabin
CHECK OUR WORK:-
13 × 16 = 208
We were RIGHT!!
So, at dis camp 16 campers sleep per cabin.
Hope I helped ya!!
