The degree of a polynomial is the highest power of its terms.
The power of a term is the sum of the powers of all the variables in a term.
A polynomial is written starting with the greatest power in standard form.
In the first case, the power of the first term is 3, the power of the second is 3 (2 from x + 1 from y) but the power of x has decreased so it is the second term, and then so on.
In the second case, the power is starting form 2 and then increasing to 3. This is incorrect.
Therefore, Marcus' suggestion is correct.
Answer:
8.75h = 50
Step-by-step explanation:

$8.75h = $50
Martin will earn $350 for 28 hours of work.
Step-by-step explanation:
Given,
Amount earned in 7 hours = $87.50
Ratio of time to amount earned = 7:87.50
Let,
x be the amount earned in 28 hours.
Ratio of time to amount earned = 28:x
Using proportion;
Ratio of time to amount earned :: Ratio of time to amount earned

Product of mean = Product of extreme

Dividing both sides by 7

Martin will earn $350 for 28 hours of work.
