Question

A new table is on sale for 15% off. If the sale price is $340, what was the original price?

Answer 1

Answer:$400

Explanation:

Let them original price be cp

Selling price=340

Percentage decrease=15

Percentage decrease=(cp-sp)/sp x 100

15=(cp - 340)/cp x 100

Cross multiplying

15cp=100(cp-340)

Opening brackets

15cp=100cp-34000

Collect like terms

100cp-15cp=34000

85cp=34000

Divide both sides by 85

85cp ➗ 85=34000 ➗ 85

cp=400
