Question

Fidel earns a fixed amount, m, for each television he sells, and an additional $15 if the buyer gets extended warranty. Fidel sells 12 televisions with extended warranties, earning $900. Write an equation to represent the situation. Then solve the equation to find the amount earned for each television sold.

Answer 1

The equation 12m+180=900 represent the situation and Fidel earns $60 for each television sold.

Step-by-step explanation:

Given,

Amount earned by Fidel for each TV = m

Additional amount for extended warranty = $15

Televisions sold = 12

Amount of televisions sold = $900

According to given statement;

Amount earned by each TV * Number of TV + Additional amount * Number of TV = Total amount

12m + 12*15 = 900

$12m+180=900\\12m=900-180\\12m=720$

Dividing both sides by 12

$\frac{12m}{12}=\frac{720}{12}\\m=60$

The equation 12m+180=900 represent the situation and Fidel earns $60 for each television sold.
