I Margaret bought a piece of fabric that is
45 inches wide and 25 yards long. She
used a piece of the fabric measuring 45
inches wide and 24 inches long to make a
doll dress. She used the remainder to
make a sundress for herself. What length,
in inches, did Margaret use to make her
sundress?
13.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
