Question

Fatima wants to purchase a scarf for `$45.00` and a sweater for `$77.50`. If she currently has `$100`, how much more money does she need to purchase the two items?

Answer 1

Fatima requires `$22.50` more in order to purchase the scarf and sweater.

Explanation:

The total cost `(x)` of the two items that Fatima wants to purchase is:

`x=45+77.50`

`x=122.50`

Since Fatima has `$100` with her, the amount `(y)` she requires to purchase those items is:

`y=122.50-100`

`y=22.50`
