Answer:
Ashley bought 6 rainbow stickers and 8 balloon stickers for her little sister.
Step-by-step explanation:
Let the number of rainbow sticker be x and number of balloon stickers be y.
Cost a single rainbow sticker= 6 cents
Cost a single balloon sticker= 4 cents
Cost a single x rainbow sticker= 6 cents × x
Cost a single y balloon sticker= 4 cents × y
Total number of stickers bought = 14
x + y =14 ..[1]
Total money spend on stickers = 68 cents
6x cents+4y cents=68 cents
...[2]

x = 14 - y
x = 14 -y =14 - 8 = 6
