Astereo at an electronics store originally costs $300, but it is on sale for 25% off. if a customer buying the stereo has a coupon for $40.00 off of any purchase, what will his final price be on the stereo?

$185

Step-by-step explanation:

Given: The original cost of the stereo at an electronics store= $300

Discount on the stereo= 25%=0.25

The price of stereo after discount= $300-0.25 of $300

If a customer buying the stereo has a coupon for $40.00 off of any purchase, then the final price of the stereo = $225-40=$185

Hence, the final price of stereo which customer has to pay=$185

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
