A school vending machine sells cartons of milk and juice. On a typical day:
No cartons are sold between 7 A. M. and
8 A. M., or from 5 P. M. onward.
The machine has a capacity of 100 cartons.
At 7 A. M., it is three-quarters full.
From 8 A. M. to 10 A. M., 10:15 A. M. to noon, and
from 1
1 p. M. to 3 P. M. the students are in class.
The machine is filled at 11 A. M. and at 4 P. M.
Sketch a graph of the number of cartons in the
vending machine as a function of time. Explain
what each section of the graph represents.

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
