Answer:
2.81
Step-by-step explanation:
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.
The equation to use here is 3^x = 81. You could start to try numbers, and you would realize that x = 4 weeks.
When solving problems like these, the easiest thing to do is either turn both fractions into decimals or into fractions with a common denominator.
So 3/4 = 0.75 OR 9/12
And 2/3 = .666 OR 8/12
In solving the actual question, you're looking for the store that gives the better deal, meaning that they sell MORE apples for LESS.
The first store sells 9/12 of a bushel for $9 and the second store sells 8/12 of a bushel for $8.
The answer is the first store which sells 3/4 of a bushel for $9.
