So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.
In summary she must work 9 hours

Answer:
<h2>a = 3.45</h2><h2>b = 6.67%</h2>
Step-by-step explanation:
Initial prediction of sales = 45 automobile
Actual amount sold = 48 automobiles
Absolute error ratio a = actual amount sold - initial prediction/initial prediction
Absolute error ratio a = 48-45/45
Absolute error ratio a = 3/45
%error = actual amount sold - initial prediction/initial prediction * 100%
% absolute error = 48-45/45 * 100
% absolute error = 3/45 * 100
% absolute error b = 6.67%
