The first thing we must do for this case is to define variables.

We have then:

x = british pound

y = dollar bills

We have the following system of equations:

x + y = 17

1.65x + y = 18.30

Resolving we have:

x = 2

y = 15

Answer:

you have:

american dollars = 15 items

british pound coins = 2 items
