Answer:
pounds.
Step-by-step explanation:
To find how much butter Robin had after baking, we first need to find how much she initially had.
According to the problem Robin had 7/8 of a pound of butter.
She used 1/4 of a pound of butter to make a cake.
This gives us:
Since we have different denominators, we need to first find the LCD of the fractions.
Now that they have the same denominators, we can then subtract them directly.
pounds.
Answer:
You will need 220 mL of the 60% solution and 80 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 50% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.5x + y)/300 = 0.65 ⇒ 0.5x + y = 190
x + y = 300
Solving the sistem of equations:
x = 220 and y = 080
Therefore, You will need
220 mL of the 60% solution
and 80 mL of pure alcohol.
