Answer:
She saved $7.5 using coupon
Step-by-step explanation:
The bill of restaurant is $ 50
We are given that Natalia wants to tip the server 20% of the original bill
So, Amount of tip = [tex]20\% \times 50[/tex]
Amount of tip =[tex]\frac{20}{100} \times 50[/tex]
Amount of tip = 10
So, Total amount = 50+10=$60
We are also given that she has a 15% off coupon
So, Amount saved using coupon = [tex]15\% (50)=0.15(50)=7.5[/tex]
So, she saved $7.5 using coupon
