Karen has a base salary that is $2100 and does not depends on how many copies she sells.
Additional to the base salary, she gets $50 for each copy she sells, so we can write this additional salary as 50*N, being N the number of copies she sells.
Then, we can write the total pay P as:
Then, if N=22, we can calculate the total pay as:
Answer:
The equation relating P and N is P=2100+50N.
The total pay when she sells 22 copies is $3,200.

Hey there! :)
Answer:
16 m².
Step-by-step explanation:
Find the surface area by finding the areas of each face:
The base is a square, so use the formula A = s²
A = 2²
A = 4 m².
Find the areas of the congruent triangular lateral sides. Use the formula:
A = 1/2 (bh)
A = 1/2 (2 · 3)
A = 1/2 (6)
A = 3 m².
There are 4 triangular faces, therefore:
3 × 4 = 12 m².
Add up the areas from the triangles and square base:
12 + 4 = 16 m².
Therefore, the surface area of this square pyramid is 16 m².
