Help Please. Adam buys 3 notebooks that each cost the same amount and 1 calculator that costs $129.99. The total cost is $147.93. How much does each notebook cost?

$5.98

Step-by-step explanation:

Take the calculator out of the total cost:

147.93 - 129.99 = 17.94

Divide the total cost of the notebooks by the amount of notebooks bought:

17.94/3 = 5.98

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:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
