If they already have $175, they need $250 more dollars. At $8 a water bottle, they would need to sell at least 32 more bottles.
55 g x 25 days = 1375 grams
1gram = 0.001 kg
1375 x 0.001 = 1.375 kg
round the answer as needed
<span>5x + 20 = -5x
5x + 5x = -20
10x = -20
x = -20/10
x = -2</span>
So 20% is 1/5 as a percent.
So 1/5 multiplied by 5 equals 5/5, or 1.
So if 1/5 = 6, then 6 multiplied by 5, or 30, must equal 5/5, or 1.
So the total number of dolls in Amyia's doll collection is 30.
