1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.

Answer: The friend won the round.
Step-by-step explanation:
We want to find the lowest score.
The lowest score means the smallest value.
With intergers, as the number gets farther away from zero to the left, the smaller the value is. The middle number is zero on a number line. The numbers to the left of zero are negative. The number to the write of zero are positive.
As you move to the left on the number line, the numbers get smaller. As you move to the right on a number line, the values get bigger
Since -4 is farther away from zero to the left on a number line than -3, -4 is smaller.
Hence -4 is smaller than -3. -4 is one more to the left than -3 so -4 is smaller than -3.
Hence the friend won the round.
50 is not a perfect square because it does not have a perfect square root where as 49 is 7, 121 is 11, and 1 is 1
