Question

Eric bought lunch for him and his friends at Papa's Pizza. His bill was $50 with tax. If he used a 15% off coupon and then left a 20% tip based on the discounted ticket, how much did he have left out of $100 bill?

Answer 1

Answer:

49

Step-by-step explanation:

50*0.85 (15% off) = 42.5, 42.5*1.20 (20% tip) = 51, 100-51 = 49

Answer 2

Answer:

$49

Step-by-step explanation:

We have been given that Eric bought lunch for him and his friends at Papa's Pizza. His bill was $50 with tax. If he used a 15% off coupon and then left a 20% tip based on the discounted ticket.

First of all, we will find amount of bill after 15% discount by finding 85% of $50 as:

$\text{Bill after 15 percent discount}=\ 50\times \frac{85}{100}$

$\text{Bill after 15 percent discount}=\ 50\times 0.85$

$\text{Bill after 15 percent discount}=\ 42.5$

Amount paid in tip would be 20% of $42.5, so total amount paid after 20% tip would be 42.5 plus 20% of $42.5.

$\text{Total amount of bill after tip}=\ 42.5+\ 42.5\times \frac{20}{100}$

$\text{Total amount of bill after tip}=\ 42.5+\ 8.5$

$\text{Total amount of bill after tip}=\ 51$

Now, we will subtract $51 from $100 to find amount of change that is $\ 100-\ 51=\ 49$

Therefore, Eric will get $49 in change.
