... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction
_____
In the real world, it seems probable that Samantha will be offered the choice of using the coupon <em>or</em> the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.
The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.
Answer:
$68 and $10.792
Step-by-step explanation:
The computation is shown below:
The total bill received by them is $56.80
The total bill after adding 19% tip is
= Total bill + tip amount
= $56.80 + 19% of $56.80
=$56.80 + $10.792
= $67.592
= $68
The sever would make the amount i.e. equivalent to the tip amount i.e $10.792
