Answer
The upward force on the parachute from the air is $~~620~N$
Work Step by Step
Let $F_a$ be the upward force on the parachute from the air. We can find $F_a$:
$(m_1+m_2)~g-F_a = (m_1+m_2)~a$
$F_a = (m_1+m_2)~(g-a)$
$F_a = (80~kg+5.0~kg)~(9.8~m/s^2-2.5~m/s^2)$
$F_a = 620~N$
The upward force on the parachute from the air is $~~620~N$
