Soup

On Monday, we cooked 25 pots and ten boilers of soup. On Tuesday, we cooked 15 pots and 13 boilers. On Wednesday, we cooked 20 pots, and on Thursday, we cooked 30 boilers. The same amount of soup was cooked on Monday and Tuesday. How many times is more soup cooked on Thursday than on Wednesday?

Correct answer:

n =  5

Step-by-step explanation:

$$\begin{gathered} 2a+10b=15a+13b \\ 10a=3b \\ a=\frac{3}{10}b \\ n=\frac{30b}{20a}=\frac{30b}{20\cdot \frac{3}{10}b} \\ n=\frac{30b}{6b}=30/6 \\ n=30/6=5 \end{gathered}$$
