Answer:
Z = 20
Step-by-step explanation:
3 x 20 = 60
60 - 12 = 48
Dan had 52
shown work: 29 x 2=58 58-6=52
3/4 foot is 9 inches, and 4 1/2 feet is 54 inches, so, 54/9 makes exactly 6 pieces of string.
We can display the information given as an equation:
2000 *

= 4000; r = increase per annum
Now, we rearrange and solve for r:

= 2
r =
![\sqrt[19]{2}](https://tex.z-dn.net/?f=%20%5Csqrt%5B19%5D%7B2%7D%20)
= 1.037.....
We can now work out the increase for 5 years like so:
2000 *

= 2400.205..... ⇒
$2400
The Table is the greater unit rate!
