Answer:
0.0398 dollars
Step-by-step explanation:
We are told in the question that
An apple picker in China earns an average wage of 45 cents per hour.
Mathematically
1 hour= 45 cents............ Equation 1
An apple picker can harvest about 2.0 bushels of apples each hour.
Mathematically
2.0 bushels = 1 hour ..............Equation 2
We are told that each bushel contains about 126 apples
1 bushel = 126 apples
2 bushels =
126 × 2
= 252 apples
Combining Equation 1 and 2 together,
We can say
An apple picker in 1 hour harvests 2 bushels of apples which is 252 apples and is paid 45 cents
1 hour = 2 bushels of apples
1 hour = 252 apples
1 hour = 45 cents
Hence we can say fro harvesting 252 apples, an apples picker is paid 45 cents
Mathematically,
252 apples = 45 cents
One gallon of apple juice requires 40 apples
We are to calculate the labor cost of one gallon of apple juice in dollars
If : 252 apples = 45 cents
40 apples = X cents
Cross Multiply
40 × 25 = 252 × X
X = (40× 25) ÷ 252
X = 3.984063745 cents
Hence the labor cost of 40 apples = 3.984063745 cents
Approximately = 3.98 cents
Converting 3.98 cents to dollars
100 cents = 1 dollar
3.98 cents =
= 3.98/100
= 0.0398 dollars.
Therefore, the labor cost of one gallon of apple juice in dollars is 0.0398 dollars.
is left, that means 
was spent. So
