If she shot her average she would make 30 out of 50 shots (AKA 60%) She could use the index cards to record each shot, recording 5 results on each one of the 10 cards
I understand this answer is really late for you but I hope you can still use it or someone else can use it if they have the same assignment
This means that the bicycle was discounted in total by 60%, so $315 is 40% of the original price to get 40% to 100% youd multiply it by 2.5 so so the same to the price 315 x 2.5= 787.5
