Total bill amount = $ 189
Step-by-step explanation:
Given:
The bill amount = $ 175
Coupon = 10%
Coupon amount = [tex]\frac{10 \times 175}{100}[/tex]
[tex]=\$ 17.5[/tex]
Bill Amount after applying the coupon = [tex]=\$ 175-\$ 17.5=\$ 157.5[/tex]
Tip = [tex]20 \% \text { of } 157.5[/tex]
= [tex]\frac{20 \times 157.5}{100}=\$ 31.5[/tex]
So the tip amount = $ 31.5
Total bill amount after the coupon and tip = [tex]\$ 31.5+\$ 157.5=\$ 189[/tex]
So the total bill amount is $ 189.
