To find the answer, we can first find the amount of oranges she has that was for sale. As she gave away 242, we can deduct 242 from the original amount 1250:
1250-242
= 1008
Then we can find the amount of bags she has by dividing the amount above by 8:
1008/8
=126 bags
As she sold for $3 for each bags, we can multiply the total amount of bags by 3:
126x3
=378
Therefore, she received $378.
Hope it helps!
