Answer:

425.83$

Explanation:

everything discounted by 30% is the same as 60% of the original price. (because 100-30 = 60)

so, to get a new, discounted price price you'd multiply the old price by 0.60

however, you're given the discounted price, so you know that

x * 0.60 = 255.50

0.60x = 255.50

x = 255.50/0.60

x= 425.83$

Goodluck with your schoolwork/homework.
