Question

Jade and Henry work for a company that sells buckets of popcorn. The company wants to have a special offer.

Here is Jade's idea for the special offer.
Put 20% more popcorn into each bucket and do not change the price.

Here is Henry's idea for the special offer.
Reduce the price and do not change the amount of popcorn in each bucket.

Henry wants his idea to give the same value for money as Jade's idea.

By what percentage, to the nearest whole number, does Henry need to reduce the price?

Answer 1

17%

Explanation:

17%

Explanation:

Jade:

p-price

so 100%+20%=120% for the amount of cereal

Find 100%

120%=p

divide by 6

20%=p/6

times by 5

100% = 5p/6

Henry:

5p/6=83% Its the same amount of cereal but for 83% of the price

so 100-83=17%

which is the reduction
