If Jaclyn has 30 times as many apples as her sister and her sister has 8 stickers, we can find out how many stickers Jaclyn has by multiplying her sister's number of stickers by 30.
Stickers Jaclyn has = 30 * (Stickers her sister has)
Stickers Jaclyn has = 30 * 8
Stickers Jaclyn has = 240
So, Jaclyn has 240 stickers.
