Answer: Daria earns a fixed amount of $55 for each television.

Step-by-step explanation:

Let a represent the fixed amount that Daria earns for each television.

Daria earns a fixed amount for each television and an additional $25 if the buyer gets an extended warranty. This means that if she sells b televisions with extended warranties, the total amount that she would earn is

ab + 25b

If Daria sells 14 televisions with extended warranties, she earns $1,120. Therefore,

14a + 14 * 25 = 1120

14a + 350 = 1120

14a = 1120 - 350

14a = 770

a = 770/14

a = 55
