Now if the lemonade is 1.50 he can only buy two because the total amount is 8.30 so it will be 3.00 and the amount left will be 5.00 and you can only buy one cupcake so you will buy two lemonades one cupcake
What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75) then I multiplied .75 by 1.20 and .9 So she spent 90 cents on apples Hope I helped :)
