Kathryn made 38 ice lollies, Sok Sang made 15 ice lollies and Bee Lian made 78 ice lollies. After Kathryn gave an equal number of ice lollies to Sok Sang and Bee Lian, the ratio of the number of ice lollies that Sok Sang had to the number of ice lollies that Bee Lian had became 2 : 9. How many ice lollies did Kathryn have left?

the answer is 99.

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

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
