You have to divide 450 and 1800 in order to find the ratio of money spent out of the income on food, then multiply that decimal by 100 in order to convert into a plausible percentage; in this case, it is 25%.
The fraction would stay the same but if you want a decimal form it would be 0.26
If

then using the chain rule, we have


Then

Step-by-step explanation/Answer:
<u><em>The value for h(3) is 1.</em></u>
<u><em>Coordinate (3,1)</em></u>
The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.
So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:
<u><em>Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.</em></u>
