Apple bowl remaining

There were 10 apples in the bowl. There were 35 apples in the bucket. Ivan transferred 15 apples from the bucket to the bowl. Then Zora took 4 apples from the bowl. Mom took 2/3 of the remaining apples in the bowl for the pie. How many apples are left in the bowl?

Final Answer:

m₄ =  7

Step-by-step explanation:

$$\begin{gathered} m_1=10 \\ {v}_1=35 \\ {m}_2=m_1+15=10+15=25 \\ {v}_2=v_1-15=35-15=20 \\ {m}_3=m_2-4=25-4=21 \\ {v}_3=v_2=20 \\ {m}_4=m_3-\frac{2}{3}\cdot m_3=21-\frac{2}{3}\cdot 21=7 \\ {m}_4=v_4=v_3=20=7 \end{gathered}$$
