The average weight per adult is 150 pounds, and the average weight per child is 40 pounds . The maximum weight is 1,500 pounds.
AnnZ [28]
With the ten children already in the elevator, the weight is at 400 pounds. Therefore you have 1,100 pounds before reaching the maximum weight. So about 7 adults can get in.

You know that your bill before tax is $52.60 and that sales tax rate is 8%. You decide to leave a 20% tip for the waiter. How mu
timofeeve [1]

Answer:

$10.52 tip should be given to the waiter.. The total bill including tax is $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax amount = $52.60

Tip percentage = 20%

Tax percentage = 8$

Tip value =

20\% \times 52.60\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52\$

Thus, $10.52 tip should be given to the waiter.

Tax value =

8\% \times 52.60\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21\$

Total bill =

Pre tax amount + Tip + Tax

=52.60 + 10.52 + 4.21\\=67.33

Thus, the total bill including tax is $67.33
