3.12

Step-by-step explanation:

total ratio=5

ratio of orange juice in 3 litres=1/5×3

ratio of lemonade in 3 litres=4/5×3

cost of orange juice=3/5×1.2

cost of lemonAde=12/5×0.8

total cost =1.2+1.92

=3.12

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
