Equations for the acceleration:
Step-by-step explanation:
The acceleration of a body is the rate of change in velocity of the body; it is given by
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
The equation can be also written as
Therefore, these two equations can be used to find the acceleration.

The price of less expensive equipment is $1575.
Step-by-step explanation:
Let,
Price of one equipment = x
Price of other equipment = y
According to given statement;
x+y=4000 Eqn 1
x = y+850 Eqn 2
Putting Eqn 2 in Eqn 1
Dividing both sides by 2;
Putting y=1575 in Eqn 2;
The price of less expensive equipment is $1575.
