There are 10 fruit punch, 12 lemonade, 6 kiwi berry, and 8 cherry juice pouches in a cooler. Stacey randomly picks a juice pouch
Leya [2.2K]
The answer is d. because there are 35 pouches.

Fruit Punch = 10/36 = 0.277778
Lemonade = 12/36 = 0.3333
Kiwi Berry = 6/36 = 0.16667
Cherry =  8/36 = 0.222222

Since she does it 120 times, multiply each decimal by 120.

Fruit Punch = 0.277778 * 120 = 33
Lemonade = 0.3333 * 120 = 40
Kiwi Berry = 0.16667 * 120 = 20
Cherry = 0.222222 * 120 = 27

The closest answer choice is d. That's why the answer is d.

Hope this helped☺☺

What number is 120% of 70
kaheart [24]

70/x=100/120
(70/x)*x=(100/120)*x       - we multiply both sides of the equation by x
70=0.833333333333*x       - we divide both sides of the equation by (0.833333333333) to get x
70/0.833333333333=x
84=x
x=84

now we have:
<span>120% of 70=84</span>
