The t-shirts for the fundraiser will cost $4.00 to make and there is a $25.00 delivery fee. There are two sized wristbands; a large one that will cost $5.00 to make, and a small one that will cost $3.00.
1. Write an expression to represent the student council's total cost of ordering t amount of T-shirts.
t x 4.00 + 25.00?
2.If everyone who orders wristbands orders one small and one large wristband, write two equivalent expressions to represent the cost the student council will have to make to have the wristbands made.
350 + $5.00 + $3.00 (I need help with figuring out the other equivalent expression)
3. Explain how you know that the two expressions from question 2 are equivalent using mathematical terms such as product, quotient, factor, sum, and coefficient.
I need help with number two so that I can try to figure this out by my self.
#1 ok, though I'd write it as
4.00t + 25.00
Lose all that "x" stuff, if for no other reason than because "x" is often used as a variable. "*" is better for explicit multiplication.
where did 350 come from? If t shirts are ordered, then t of each of the band sizes will as well, so the cost of the bands is
t(5.00+3.00) = 8.00t
the distributive property of real numbers makes sure that they are the same.
For number 2 I figured out the answer so I do not need help with that one.
350 is the amount of students that can order wristbands
For number 3 I need for help on how to do that one
