The correct selling price is about $20, and the likely mistake was the manager multiplied the $12 by .67 (the 67%), got about 8, and took that as the price instead of adding it to the original 12, which is what they were supposed to do.
$1.80 is your answer.
If you divid 5.76 by 3.2
It fits because you can reverse and multiple 1.8 by 3.2 to get 5.76
They try to trick you by making it a .2 lb.
A)
d =240/a
B) 2 loads of gravel
Step-by-step explanation:
Step 1:
Given one load of gravel is 240 ft2.
We have depth = 240/area
Hence the inverse variation model is d =240/a
Step 2 :
The length and breadth of the playground is 40 ft and 24 ft
The depth of the playground is 6 in = 6/12 ft
Hence the volume of the given playground is 40 * 24 * 6/12 = 480 cu ft.
There is 240 ft2 of gravel in one load
So we need 480 cu ft of gravel = 480/240 = 2 loads of gravel.
A. is true because 2+2 does = 4 and 1 +1 =2
B is false because 2 +3=5
Count by ones from 392 to 500ok done
im not about to write all that out
