Three hikers started climbing with each hiker carrying 7.8 kilograms of weight. A fourth hiker joined them and they divided the total weight of hiking equipment evenly. How much did each hiker have after the 4th person joined? (Round your answer to two decimal places)

5.85 kilograms

Step-by-step explanation:

We are told that Three hikers started climbing with each hiker carrying 7.8 kilograms of weight.

Thus, total weight carried by them = 7.8 × 3 = 23.4 kilograms

Now a fourth person joined them and they divided the weight equally.

Thus, each hiker will now carry;

23.4/4 = 5.85 kilograms

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
