0.63636363636363636
Step-by-step explanation:
14/22
If each tire in the front of the car cost $12.40 more than the rear tires, then the total would be $24.80. And because we say that each tire for Luke's race tire is going to cost him $100 each, he would be paying $224.80 for the two front tires, while including both the cost of each tire and the additional 12.40.
Equation: 12.40(2) + 100(2) = 224.80
The first place and 15th place are already decided, so we have to find the number of <span>different ways that the </span>other<span> 13 students can line up, in the places from 2 to 14.</span>
2nd place can be any one of 13 people. For each of those . . .
3rd place can be any one of 12 people. For each of those . . .
4th place can be any one of 11 people. For each of those
13th place can be any one of 2 people. For each of those
14th place has to be the one student who is left.
Total number of ways that 13 students can line up in places 2 through 14 is
(13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)
<span>That number is called "thirteen factorial". The number is </span>6,227,020,800<span> . </span>
<span>When you write it in math, you write it like this:</span><span>13</span>
441 + 14(1.50) = 462
462 / (2.00+1.50) = 132
132 - 14 = 118
132 adult plates were served and 118 children plates were served.
