Question

A shop has two offers.

Without a Store card
With a Store card
1
3
off normal prices
45% off normal prices
Laura is going to buy a coat in the shop.
The normal price of the coat is £90
Laura would pay less with a Store card than she would pay without a Store card.
How much less?
can: 3=30

Answer 1

We can easily see that 45% is larger than 1/3, so the second option is better, and to calculate it 45 percent of 90 is 40.5, and 1/3rd of 90 is 30, so Laura would pay 49.5 and 60, the 2nd option would have her pay 10.5 dollars less than the 1st option
