The amount saved is $7.5, the tip is $10, and the total bill is $52.5. The results are obtained by multiplying percent value by the original bill. The total bill is the original bill minus the discount plus the tip.
How to calculate the bill payment?
We, sometimes, have a coupon of discount for any bill. So, the total bill is not always the same with the original bill.
In case that Natalia has
- The original bill $50
- 15 % off coupon
- The tip 20% of the original bill
How much is the amount saved using the coupon, the tip, and the total bill payment?
The amount saved (discount) is
= percent of discount × the original bill
= 15% × $50
= 0.15 × $50
= $7.5
The tip is
= percent of the tip × the original bill
= 20% × $50
= 0.2 × $50
= $10
The total bill is
= the original bill - the discount + the tip
= $50 - 7.5 + $10
= $52.5
Hence, the amount saved is $7.5, the tip is $10, and the total bill is $52.5.
