Bill and Ted are going to order t-shirts for there school clubs. The t-shirts will have the club logo printed on the front. Bill and Ted ask two local t-shirt companies to give them a price. * Patty's Printing charges $21.50 for each t-shirt. * Sandra's shirts has a one-time set up fee for $63 and then charges $18 for each t-sh
Step-by-step explanation:
Part 2: Table Chart:
Number of t-shirts: 2
Patty's cost: 43$
Sandra's cost: : 99$
Number of t-shirts: 4
Patty's cost: 86$
Sandra's cost: : 135$
Number of t-shirts: 6
Patty's cost: 129$
Sandra's cost: : 171$
Number of t-shirts: 8
Patty's cost: 172$
Sandra's cost: : 207$
Number of t-shirts: 10
Patty's cost: 215$
Sandra's cost: : 243$
Number of t-shirts: 12
Patty's cost: 258$
Sandra's cost: : 279$
Number of t-shirts: 14
Patty's cost: 301$
Sandra's cost: : 315$
Number of t-shirts: 16
Patty's cost: 344$
Sandra's cost: : 351$
Number of t-shirts: 18
Patty's cost: 387$
Sandra's cost: : 387$
Part 3: Patty's Printing
Linear equation = equation of a line= y=mx+b
y=21.5x
Part 4: Sandra's Shirts:
Linear equation = equation of a line= y=mx+b
y= 18x+63
Part 5: Note to Jackie
Dear Jackie, I recommend Sandra's shirts.
Write equations:
Sandra's Shirts = 18x+63
Patty's Printing = 21.5x
Sandra's Shirts: 495=18x+63 = 24 shirts
Patty's Printing: 495=21.5x = 23 shirts
Part 6: Refute Jackie
Sandra's Shirts is more expensive at the beginning, but as you buy more shirts (greater than 18), Patty's Printing becomes cheaper.
You should probably add to this, but I can't think of anything else.
Part 7: Equality
At 18 shirts (see table), the shirt cost is equal.
You should probably add to this, but I can't think of anything else.
18x+63=21.5x
Words of encouragement:
Good luck!
