Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p
