Picture graphs usually show amounts using...pictures! So if you looked
at the symbols, you can likely guess the amounts. It might show how many
students preferred hamburgers by using a hamburger to represent every 5
students. Just by quickly glancing at a picture graph, you can usually
tell which result is the greatest.
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:
Step-by-step explanation
- Amount of discount: 20%= 0.20; 0.20×42= $8.4
- Sale price: $42-$8.4= $33.6
For interest question, plug in the values:
P= $3200
r= 3%÷100 = 0.03
t= 4 years
Calculate:
I=Prt
= 3200×0.03×4
=$384
Answer:
simple.
