Answer: The concentration of X is
and the concentration of Y is
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes

By solving these two equations, we get that

Hence, the concentration of X is
and the concentration of Y is
.
Answer:
x ≥ 767
The number of bags sold must be greater than or equal to 767 to make a minimum profit of $6900.
Step-by-step explanation:
If they want a profit of at least $6900, then the total amount earned would have to be ≥ 6900. You can always earn more than $6900, but the lowest should be equal to $6900.
So if we use x as the number of bags sold, and we know that each bag will earn $9, then x • 9 ≥ 6900.
If we divide both sides by 9, then the number of bags sold must be ≥ 767.
