selina bought a shirt on sale that was 20% less than its original price. the original price was $5 more than the sale price. what was the original price? explain your answer.

The original price was $25

Step-by-step explanation:

where p is the original price of the shirt, the sale price of the shirt is .80p.

the sale price of the shirt is p - 5.

so you can use this equation:

.80p = p - 5

now solve for p.

.80p - 1p = -5

-.20p = -5

p = 25.

so the original price was $25 and the sale price was $20.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
