Sales Daria sells televisions. She earns a fixed amount for each television and an additional $25 if the buyer gets an extended warranty. If Daria sells 17 televisions with extended warranties, she earns $1,445. How much is the fixed amount Daria earns for each television?​

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

y = b

Step-by-step explanation:

~Solve for y~

Let's solve for y.

4y=6y−2b

Step 1: Add -6y to both sides.

4y+−6y=−2b+6y+−6y

−2y=−2b

Step 2: Divide both sides by -2.

−2y

−2

=

−2b

−2

y=b

y=b
