Question 805678: Please help me solve this: How much water should be added to 30 quarts of juice that is 70% juice to get a diluted mixture that is 60% juice?
My work: Let w = the amount of water needed
30+w= the total amount of the mixture
100w + 2100 = 60(30+w)
100w + 2100 = 1800 +60w
-60w + 100w + 2100 = 1800 + 60w + (-60w)
40w + 2100 =1800
-2100 + 40w + 2100 = 1800 + -2100
40w = -300
1/40(40w)=-300(1/40)
w = -7.5
How can you add negative amounts of water?

Question 805745: How much of a cream base must be mixed with 20g of 0.5% dexamethasone and 75g of 0.025% of dexamethasone and 30g of 0.05% dexamethasone to make 0.02% of dexamethasone cream ?
My own calculation : 20g x 0.5% = 0.1
75g x 0.25% = 0.1875
30g x 0.05% = 0.015
20g + 75g + 30g = 125
0.1 + 0.1875 + 0.015 = 0.3025/ 0.02% = 1512.5
1512.5 - 125 = 1387.5g
But the right answer 1375g Who solve it for me
