First find the number of nougats by doubling the number of caramels: 3 caramels * 2 nougats/caramel = 6 nougats Then find the number of truffles by adding 7 to the number of caramels: 3 caramels + 6 = 9 truffles Then find the number of peanut clusters by subtracting the number of each other chocolate from the total number of chocolates: 50 chocolates - 3 caramels - 6 nougats - 9 truffles = 32 peanut clusters Finally, divide the number of peanut clusters by the total number of chocolates and multiply by 100% to find the percentage chance he gets a peanut cluster: 32 peanut clusters / 50 chocolates *100% = 64%

Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = 5 rows of tomato plants. This gives her enough room to plant 5 rows * 8 plants/row = 40 tomato plants. The plants will produce a total of 40 * 3 = 120 tomatoes.

Paige has 100 space stickers that she is dividing among 3 friends, so 100 stickers / 3 friends = 33 stickers for each friend, with 1 remaining. She also has 50 cat stickers that she is diving among 3 friends, so 50 stickers / 3 friends = 16 stickers for each friend, with 2 remaining. So Paige will have 1 remaining space sticker + 2 remaining cat stickers = 3 stickers left.

If three-quarters of the boxes are full, then 1 – ¾ = ¼ of the boxes are half-full. On average, each harvest therefore has 20 boxes * 0.25 = 5 boxes that are half-full. This leaves 20 total boxes – 5 half-full boxes = 15 full boxes. Half-full boxes hold 20 parsnips / 2 = 10 parsnips each. In total, the half-full boxes, therefore, hold 5 boxes * 10 parsnips = 50 parsnips. The full boxes hold a total of 15 boxes * 20 parsnips = 300 parsnips. So Betty harvests a total of 50 + 300 = 350 parsnips in an average harvest.
