Step-by-step explanation:
The degree of an algebraic expression is the largest exponent of the variable present. In expressions with multiple variables, the exponents of each variables are added.
First Expression;
pq: Degree = 1 + 1 = 2
p²q: Degree = 2 + 1 = 3
p²q²: Degree = 2 + 2 = 4
The degree of this expression is 4
Second Expression;
2y²z: Degree = 2 + 1 = 3
10yz: Degree = 1 + 1 = 2
The degree of this expression is 3

The cost Esme increased was 200, but then she reduced 20%of 700, which gives 140 dollars reduced. So, we subtract 140 from 200, which is 60 to find the actual increase.
Now, we follow the simple rules of percentage change
Increase divided by original times 100.
So, 60 divided by 500( not 700) times 100 = 12
