The table shows how the number of sit-ups Maria does each day has changed over time. At this rate, how many sit-ups will she do on day 12? day 1- 17, day 2- 21, day 3- 25, day 4- 29, day 5- 33

61

Step-by-step explanation:

a = 17

d = 21 - 17 = 4

12th day: 17 + 4(12 - 1)

17 + 44

61

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 !
