If the original bill is $22.50, what will be the final bill after a 15% tip is paid? round to the nearest cent

Studentka2010 [4]

For this case what you should do is take 15% of 22.50 and add it to the original price. We have then:
((15) / (100)) * (22.50) = 3.375
Then, we add to the original price:
22.50 + 3.375 = 25.875
round to the nearest cent

Suppose a group of x people rent a jeep for $80 for a trip to the beach and plan to share the cost equally. If one person in the

yarga [219]

Answer:

Step-by-step explanation:

Given that a group of x people rent a jeep for 80 dollars.

Since they share the amount equally we have

each person share = $\frac{80}{x}$

When one person in the group decides not to go, each remaining person has to pay an extra 4 dollars.

i.e. now the share borne by each in the group would be

$\frac{80}{x-1}$

This is 4 dollars more than the original

Hence equation would be

$\frac{80}{x-1}-\frac{80}{x} =4$

This equation would be used to determine how many people are in the group.
