Answer: The correct choice is that he can maximize his earnings by working 12 hours as a tutor and 3 hours as a lawn mower.
James will make the most money by working at the job that pays him the most. However, he has to work at least 3 hours at $10 per hour.
Therefore, he should work only 3 mowing lawns and the rest tutoring.
Answer:
We need 8 ounces of solution A and 32 ounces of solution B.
Step-by-step explanation:
We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.
She knows that Solution A is 40% salt and Solution B is 65% salt.
- First condition states that she wants to obtain 40 ounces of a mixture that is 60
% salt, that means;
A + B = 40
B = 40 - A ------------ [Equation 1]
- Second condition states that Solution A is 40% salt and Solution B is 65% salt, that means;
{from equation 1}
A = = <u>8 ounces</u>
Now, putting value of A in equation 1, we get;
B = 40 - A
B = 40 - 8 = 32 ounces
Hence, we need 8 ounces of solution A and 32 ounces of solution B.
