bonnie pushes a box vertically up with a 300 N force, while clyde pulls the box up with a 350 N. The accelerates up at 1.2 m/s^2, what is the mass of the box? I got 66.44 kg, but I don't know if I'm right. Can someone help me?

the box accelerates up at 1.2 m/s^2. Sorry, my mistake.
they exert upward force while gravity exerts downward
f = m a ... 300 + 350 - (m g) = 1.2 m ... 650 = m (1.2 + g)
f = m a ... 300 + 350 - (m g) = 1.2 m ... 650 = m (1.2 + g)
