-5 from both sides
4k = 110
Divide 110 by 4 = 27.5
K = 27.5

<span>cost of producing x radios is c(x) = 400 + 20x - 0.2x
where:
x=number of units
thus the cost required to produce 30 units will be given by
c(30)=400+20(30)-0.2(30)
c(30)=400+600-6
c(30)=994
Answer: Marginal cost will be $994</span>
Answer:
12 ft
Step-by-step explanation:
Write and solve an equation of ratios:
6 ft 4 ft
-------- = --------
18 ft w
Cross multiplying, we get: 6w = 72 ft^2, so w = 12 ft
