Lin's father is paying for a $20 meal. He has a 15%-off for the meal. After the discount, a 7% sales tax is applied. How much is the 15% coupon worth?
I need this answered sometime today pls , if you get it right when i submit test i will give you brainliest! :)

Respuesta :

15% of 20 = 3, so the meal is $17 before sales tax is added on.
7% of 17 = 1.19
Total cost = $18.19
Without any discount the meal would have cost $21.40
So, the coupon was worth $3.21
