In the apple

In an apple orchard, 12 part-time workers were picking apples for 5 days. Their daily performance in kilograms was as follows: 155.6; 168.2; 175; 159.4; 169.5.
When calculating, round the results to hundredths.
a) On average, how many kg of apples did the workers pick daily?
b) On average, how many kg of apples did one worker pick during the whole job?
c) How many kg did one worker pick on average daily?
d) How many euros did one worker earn on average, if for one kilogram of picked apples they were paid 1.50 €?
e) How many euros did the orchard owner take in, if one kilogram he sold for 1.80 €?

Final Answer:

a =  165.54 kg
b =  68.98 kg
c =  13.8 kg
d =  103.4625 eur
e =  1489.86 eur

Step-by-step explanation:

$$\begin{gathered} n=12 \\ d=5\text{d} \\ s=155.6+168.2+175+159.4+169.5=827.7\text{kg} \\ a=s/d=827.7/5=165.54\text{kg} \end{gathered}$$

$b=s/n=827.7/12=68.98\text{kg}$

$c=s/(n\cdot d)=827.7/(12\cdot 5)=13.8\text{kg}$

$d=1.50\cdot b=1.50\cdot 68.975=103.4625\text{eur}$

$e=s\cdot 1.80=827.7\cdot 1.80=1489.86\text{eur}$
