a ring is now reduced to 840 pounds
this is a saving of 40% of the original price
b) workout the original price of the ring

a) £600

b) £1400

Step-by-step explanation:

a)

original price = x

reduced price = £420

reduced price is 70% of original price

Since the discounted price, £420, is 70% of the original price, x, then

70% of x = 420

0.7x = 420

x = 420/0.7

x = 600

£600

b)

original price = x

discounted price = £840

discount percentage = 40%

The original price is x, and x is 100% of the original price since 100% is the whole amount. The discount is 40% of the original price. 100% - 40% = 60%. That means the discounted price is 60% of the original price.

60% of x = 840

0.6x = 840

x = 840/0.6

x = 1400

£1400
