Withdrawn 15713

The ATM had 33250 euros on Monday. 10/25 was withdrawn from it on Tuesday, and 2/5 was withdrawn from the same ATM on Wednesday. How many did they pick on Tuesday, and how many on Wednesday? How many euros remained in the ATM?

Correct answer:

b =  13300 eur
c =  7980 eur
d =  11970 eur

Step-by-step explanation:

$$\begin{gathered} a=33250\text{eur} \\ b=a\cdot \frac{10}{25}=33250\cdot \frac{10}{25}=\frac{33250\cdot 10}{25}=\frac{332500}{25}=13300\text{eur} \end{gathered}$$

$c=\frac{2}{5}\cdot (a-b)=\frac{2}{5}\cdot (33250-13300)=7980\text{eur}$

$d=a-b-c=33250-13300-7980=11970\text{eur}$
