If a calendars discount price is 75% and it's sale price is $2.25. What the original price?

Let y be the original price

Yx. 25 = 2.25

.25y = 2.25

Y = 2.25/.25

Y = $9

If The Calendar Was Discounted By 75%:

100 - 75 = 25

25% = $2.25

$2.25 • 4 = $9.00

So In That Case, The Answer Would Be $9.00

If The Calendar Was 75% Of The Original Price:

75% = $2.25

$2.25 Divided By 3 = $0.75

$0.75 • 4 = $3.00

So In This Case, The Answer Would Be $3.00
