Question

you have a coupon for 30% off your dinner. your total bill was $50. you also need to pay a 7% sales tax and leave a 22% tip. with the discount, tip+tax included, how much was your dinner?

Answer 1

first, we need to calculate the amount of discount we get using the coupon:

Discount = 30% of $50

Discount = 0.30 * $50

Discount = $15

So the discounted price of the meal is:

Discounted Price = $50 - $15

Discounted Price = $35

Now we need to add the sales tax:

Sales Tax = 7% of $35

Sales Tax = 0.07 * $35

Sales Tax = $2.45

Adding the sales tax to the discounted price gives us:

Discounted Price + Sales Tax = $35 + $2.45

Discounted Price + Sales Tax = $37.45

Finally, we need to add the tip:

Tip = 22% of ($35 + $2.45)

Tip = 0.22 * $37.45

Tip = $8.24

Adding the tip to the discounted price and sales tax gives us:

Discounted Price + Sales Tax + Tip = $37.45 + $8.24

Discounted Price + Sales Tax + Tip = $45.69

Therefore, the final cost of the dinner with the discount, sales tax, and tip included is $45.69.
