24/30 = 12/15 = 4/5
this is the simplified form
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
8 and 2: 8+8+2+2
7 and 3: 7+7+3+3
6 and 4: 6+6+4+4
=20
The size of the large cabinets door = 2.3 * 11.5 = 26.45 inches
the board size in inches = 10 1/2 * 12 = 126 inches
number of doors = 126 / 26.45 = 4.76
so the number of doors = 4 doors
Well I'm just doing some random math so it might be 300?
