Expert Solution

Step 1

Natalie bought a sandwich and a hot cider for lunch. Let the number of sandwich be x and price she paid for a sandwich be Px. And the number of cider by y and the price she paid for a cider be Py.

Since we know, she bought a single sandwich a single cider. That is, x=1 and y=1

Also, she total spent $10.25 on the whole lunch. Therefore, her total spent can be represented as the following equation.

$x P x + y P y = $ 10.25$

Where,

x=sandwich=1

y=cider=1

Px= price of a sandwich

Py= price of a cider
