Answer:
c) 50 ≤ y ≤ 170
Step-by-step explanation:
range is the set of y values and y = the cost
You'd have to regroup twice.
Since 26 is bigger than 13, you'd need both the tens and ones places to go up by ten in order to subtract properly.

Step-by-step explanation:
1. Calculate the square root: 5x4+7x5
2. Multiply 5x4=20 7x5 20+35
3. 20+35=55
The first place and 15th place are already decided, so we have to find the number of
different ways that the <em>other</em> 13 students can line up, in the places from #2 to #14.
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)
That number is called "thirteen factorial". The number is <u>6,227,020,800</u> .
When you write it in math, you write it like this: 13!
