C(x) = 400 + 20x - 0.2x²
c(30) = 400 + 20(30) - 0.2(30)²
= 400 + 600 - 0.2(900)
= 1000 - 180
= 820
It costs $820 when 30 radios are produced.
Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two.
c(31) = 400 + 20(31) - 0.2(31)²
= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.
Now we find the difference which means we subtract the two.
828 - 820 = 8.
Your marginal cost is $8.
To compare we can also do 29 radios.
c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812
820 - 812 = 8.
Answer:
SAS
Step-by-step explanation:
well there exactly ths same you just add what ever inside and subtract forn 180 which is an angle
No,
3/4 * 5=3.75
3.75 is less than 6.
Answer:
x>4
Step-by-step explanation:
because x is greater than 4
Because he ended up paying $24 more than the actual price of the drill, this is the amount of interest he paid.
In total, the repairman pays $324 in 6 equal payments. So, each payment was
.
