Question

Olympia ate lunch at a restaurant. The amount of her check was $6.89. She left $8.00 on the table, which included the amount she owed plus a tip for the waiter. Which equation shows t, the amount of her tip, in dollars?

1.6.89 + t = 8.00
2.6.89 - t = 8.00
3.6.89t = 8.00
4.6.89 = 8.00 Divided by t

Answer 1

1 6.89+t=8

Explanation:

Because she left 6.89 to pay for her food and a tip. So whatever the tip was plus the 6.89 she owed equaled $8.
