Brielle and her family went to our diner. They got ice cream cone, a brownie, and a cookie. How much did they spend on dessert?

Svetlanka [38]

Answer:

$6.83

Step-by-step explanation:

A brownie costs $3.45, an ice cream costs $2.43, and a cookie costs $0.95. So $3.45 + $2.43 + $0.95 = $6.83. If you need to know the change if they paid with $10.00 also . . . That would be $10.00 - $6.83 = $3.17 change.
