Question

Daria sells televisions. She earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty. If Daria sells 11 televisions with extended​ warranties, she earns $ 715. How much is the fixed amount Daria earns for each​ television?

Answer 1

Answer: the fixed amount that Daria earns for each​ television is $50

Step-by-step explanation:

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

She earns a fixed amount for each television and an additional $15 if the buyer gets an extended warranty. Assuming she sells y televisions, her total earnings would be

xy + 15y

Daria sells 11 televisions with extended​ warranties, she earns $715. This means that

11x + 15 × 11 = 715

11x + 165 = 715

11x = 715 - 165

11x = 550

x = 550/11

x = 50

Answer 2

Answer:

$50

Step-by-step explanation:

11(X + 15) = 715

X + 15 = 65

X = 65 - 15 = 50
