Question

Mrs. Henderson used 62 yards of fabric to make 3 elf costumes. What equation can be used to model the total number of yards of fabric y for x costumes? Write the equation in the form y = kx

Answer 1

The total number of yards of fabric is y and the amount of costumes is x

If you have an equation in the form::

$y=kx$

And you know that for 3 elf costumes she used 62 yards of fabric, you have that when x = 3, y = 62. We put this into the expression above and solve for k:

$62=k\cdot3$$undefined$
