Question

Karen is a software saleswoman. Her base salary is $2100, and she makes an additional $50 for every copy of English is Fun she sells. Let P represent her total pay (in dollars), and let N represent the number of copies of English is Fun she sells. Write an equation relating P to N. Then use this equation to find her total pay if she sells 22 copies of English is Fun.

Answer 1

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:

$P=2100+50N$

Then, if N=22, we can calculate the total pay as:

$P(22)=2100+50\cdot22=2100+1100=3200$

Answer:

The equation relating P and N is P=2100+50N.

The total pay when she sells 22 copies is $3,200.
