The amount left in the fund decreases by $110 for each desk purchased.
We suspect that each new desk probably costs $110.

Answer:

$110 is the decrease in the school desk's fund for each new desk is purchased.

Step-by-step explanation:

We have to calculate the amount of money left in the school's desk fund when a new desk is purchased.

From the given link we find two points (2, 480) and (5, 150), and the decrease in fund when a desk is purchased will be denoted as

Decrease in school's desk fund after a new purchase = Change in y coordinates of the points / difference in x-coordinates

= (480-150)/(5-2) = 330/3 = $110

Answer is $110.

Use the euclidean algorithm to find
kvasek [131]
A)
18=1\cdot12+6
12=2\cdot6+0
\implies\mathrm{gcd}(12,18)=6

b)
201=1\cdot111+90
111=1\cdot90+21
90=4\cdot21+6
21=3\cdot6+3
6=2\cdot3+0
\implies\mathrm{gcd}(111,201)=3

c)
1331=1\cdot1001+330
1001=3\cdot330+11
330=30\cdot11+0
\implies\mathrm{gcd}(1001,1331)=11

d)
54321=4\cdot12345+4941
12345=2\cdot4941+2463
4941=2\cdot2463+15
2463=164\cdot15+3
15=5\cdot3+0
\implies\mathrm{gcd}(12345,54321)=3

e)
5040=5\cdot1000+40
1000=25\cdot40+0
\implies\mathrm{gcd}(1000,5040)=40

f)
9888=1\cdot6060+3828
6060=1\cdot3828+2232
3828=1\cdot2232+1596
2232=1\cdot1596+636
1596=2\cdot636+324
636=1\cdot324+312
324=1\cdot312+12
312=26\cdot12+0
\implies\mathrm{gcd}(9888,6060)=12
