Lou Zing Marbles just came back from three marble games with 21 marbles left in his pocket. In the first game, he lost ½ of his marbles. In the second game, he ended up with 12 times what he had going into that game. In the third game, he won 9 marbles. Lou forgot how many marbles he began with. Find how many he had when he started playing the three games.

8/8 6/8 so your going to take 2 from 8/8 so that would be 6/8

Step-by-step explanation:

1 is b and 2 is d

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
