Question

A skate board was originally priced at £100 on Thursday.
On Friday the price was reduced by 50%. On Saturday, Friday's price was reduced by a further 30%. On Sunday, Saturday's price was reduced by a final 10%.
What was the final percentage reduction on the original price?

Answer 1

Answer:

31.5

Step-by-step explanation:

50 percent of 100 would be 50, so you subtract 50 from 100, and 30 percent of 50 is 15, so you subtract 15 from 50 and then get 35, which 10 percent of is 3.5, and finally you subtract 3.5 from 35 and you end up with 31.5.
