Question

George and his friend Jane buy copies of the same book on the internet. George pays $16.95 and jane pays £11.99 on a day when the exchange rate is $1 = £ 0.626.

calculate, in dollars, how much more Jane pays.

Answer 1

$19.15

Explanation:

$1=0.626

$1/0.626=£1

$11.99=$11.99/0.626

=$19.15

Answer 2

Explanation:

£ 0.626 =$ 1

£1 = $
`(1)/(0.625)`

£ 11.99 =
`11.99*(1)/(0.625)= (11.99*1000)/(0.625*1000)\\\\`

`= (11990)/(626)\\\\`

= $ 19.15

19.15 - 16.95 = $2.2

Jane pays $2.20 more dollars that George
