Question

a cell phone and phone case cost 110$ in total. the cell phone costs 100$ more than the phone case. How much was the cell phone?

Answer 1

$100

Explanation:

We know that the total cost was $110 and that the phone is $100 more than the case. With this, we can figure out how much the case is, and use that information to find the price of the phone.

Case price = total price - 100

= 110 - 100

Case price = 10

Now that we know that the case price is $10, we can figure out the phone's price.

Phone price = total price - case price

= 110 - 10

= 100

The phone costs $100
