Sindrei [870]

Answer: 7/5m

Step-by-step explanation:

The initial value of the painting = m

Increase in the painting = 2/5

The final value of the painting will be the addition of the initial value of the painting and the increase. This will be:

= m + (2/5 × m)

= m + 2/5m

= 5/5m + 2/5m

= 7/5m
