To solve this we will first see how many hats Susan has left when she lets her friends borrow the hats.
45 - 3 = 42
42 - 2 = 40
So, Susan has 40 hats left after her friends borrowed some. Now lets divide to see how many hats will go in 1 cupboard.
40 ÷ 20 = 2
2 hats in each cupboard.
CHECK OUR WORK:-
20 × 2 = 40.
We were RIGHT!!!
So, after Susan's friends borrow some of her hats she can put 2 hats in each cupboard.
Hope I helped ya!!
