Idon't understand this, can someone ?

It is less than 1 because .31 + 5/9   < 1

Step-by-step explanation:

.31 - (-5/9)

.31 + 5/9

31/100 + 5/9

estimating

1/3 + 2/3

this is approximately 1

but 1/3 = .33333333  is greater than .31 and 2/3  = 6/9  is greater than 5/9

so .31 + 5/9 < 1

i really dont know

step-by-step explanation:

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
