How do you find and explain the answer?

6. Points (0, 0), (1, 1), (-1, -1), (2, 2), (-2, -2) are all on the same line which has equation y = x. The ants are always going from one point on the line to another point on the line. Also, as each ant goes from one point to the the next point, it walks a distance of sqrt(2). Since the ants started at the same point, the anthill at (0, 0), and walk in opposite directions along the same line, and each time they go from point to point, they go the same distance, they are always the same distance from the anthill (0, 0).

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

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
