Let's say that B makes $100.
Then A makes $75.
So, your question then becomes 100 is what percent of 75?
This can be solved by setting up the proportion 100 / 75 = x / 100
75x = 10000
x = 133.3
So, B's income is 33.3% more than A's income.
Answer:
I don't know soorry. lalalala
The partial derivatives are not equal, so the equation is not exact.
I think the correct one is C. 130
The error occurred in step 2. You have to use the distributive property for the parenthesis. It is supposed to be 5p+15.
The correct solution is p>-13.
