Need this answer asap plz if you can

last week chris bought a dvd for $10.80 while the store was having a 25% off sale the sale is now over at how much would the same dvd cost todaym

$14.40

Step-by-step explanation:

If you received 25% off then you paid 75% of the price. To find the original price, write a proportion.

Solve by cross multiplying.

75y = 1080

y = 14.4

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

it is contrapositive
