Answers:
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.
1D. I just did
L has "x -3"
S has "x"
x + x - 3 = 17
2x -3 (+3) = 17 (+3)
2x = 20
2x/2 = 20/2
x = 10
Leona has x - 3, or 10 - 3, or 7 dollars
Skye has 10 dollars
hope this helps
