Question

Vicky makes 8 purses and 9 key rings to sell for charity.
The price of a purse will be twice as much as the price of a key ring.
Vicky wants to get a total of exactly £40 when she sells all the purses and all the key rings. Work out the price Vicky needs to charge for each purse and for each key ring.

Answer 1

Answer:

For purse vicky should charge 3.2 and for key ring he should charge 1.6

Step-by-step explanation:

Let the price of key ring be x

then,

price of purse is 2x

according to question

40 = 8(2x) + 9(x)

40 = 16x + 9x

40 = 25x

x =40/25 = 8/5

x = 1.6
