Question

anonymous · Answer

a) replace P by 2000 solve for v in two steps
add 500, divide by 2.5

anonymous · Answer

b) replace v by 200 and compute P

anonymous · Answer

c) solve 
$$2.5v-500\geq 500$$ by adding 500 to both sides and then dividing by 2.5

callisto · Answer

a) put P=2000 into the equation
 2000 = 2.50v - 500
2500 = 2.50v
v= 1000
b) Put v = 200 into equation
p= 2.50 x 200 - 500 = 0
c) like what satellite73 said. Solve it and you'll get $$v \ge400$$
