Solve this problem :
A warehouse sells clothing at a fraction of its original cost. The table
be low shows the fraction off the original price for clothing that remains in
the warehouse after 10 days, 20 days, and 30 days.

WAREHOUSE PRICES
Item Price After 10 Days After 20 Days After 30 Days
Jacket $120 1/4 off 1/3 off 1/2 off
Shoes $40 1/5 off 2/5 off 3/5 off
Shirt $12 1/4 off 1/3 off 2/3 off

1. Find the price of the items after each 10-day period to complete the
chart below . Show how you arrived at each answer.

WAREHOUSE PRICES
Item Price After 10 Days After 20 Days After 30 Days
Jacket $120 $90    
Shoes $40      
Shirt $12     $4.00

Suppose you have $100.00 to spend.

2. Within the range of $90.00 to $100.00, what are all possible
combinations of items you could buy after 10 days?

3. Would you have enough m oney to buy 2 jackets after 20 days? Why
or why not?

4. Could you buy all 3 items if you waited until after 30 days?
