A 2-column table with 5 rows. Column 1 is labeled Miles with entries 1, 4, 7, b, 15. Column 2 is labeled Minutes with entries 7, 21, a, 70, c.
Martin’s running ability is measured by this proportion:

StartFraction 1 over 7 EndFraction = StartFraction 3 over 21 EndFraction

Use the proportion to identify the values of the variables that complete the rate table

a =
b =
c =

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

answer: the correct one is a

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
