Givens
a1 = 6
Use t4 - t3 to get d
t4 = 27
t3 = 20
Step One
Find a1 and d
a1 = 6
d = t4 - t3
d = 27 - 20
d = 7
Step Two
Find the 30th Term
tn= a1 + (n -1 )*d
t30 = 6 + (30 - 1) * 7
t30 = 6 + 29*7
t30 = 6 + 203
t30 = 209
Step Three
Find the sum using Sum = (a + t30)*n/2
n = 30 given
a1 = 6 given
t30 = 209 calculated from step 2
Sum = (a1 + t30)*n/2 Substitute
Sum = (6+ 209)*30/2 Combine like terms and divide by 2
sum = 215 * 15 Multiply
Sum = 3135 Answer
Answer:
Demand is Elastic when Price > 200 ; Demand is inelastic when Price < 200
Step-by-step explanation:
p = 400 - 4x
4x = 400 - p
x = (400 - p) / 4 → x = 100 - p/4
Elasticity of demand [ P ed ] = (Δx / Δp) x (p / x)
Δx / Δp [Differentiating x w.r.t p] = 0 - 1/4 → = -1/4
P ed = <u>-1</u> x<u> p </u>
4 (400 - p)/4
= <u>-1</u> x <u> 4p </u> = -p / (400-p)
4 (400 - p)
Price Elasticity of demand : only magnitude is considered, negative sign is ignored (due to negative price demand relationship as per law of demand).
So, Ped = p / (400 - p)
Demand is Elastic when P.ed > 1
p / (400-p) > 1
p > 400 - p
p + p > 400 → 2p > 400
p > 400 / 2 → p > 200
Demand is inelastic when P.ed < 1
p / (400-p) < 1
p < 400 - p
p + p < 400 → 2p < 400
p < 400 / 2 → p < 200

Answer:
3515
Step-by-step explanation:
Data provided in the question:
Dimension of the container = 1.5 m x 18 cm x 28 cm
volume of the container = 150 cm × 18 cm × 28 cm = 75600 cm³
also,
1 L = 1000 cm³
thus,
volume of the container = 
= 75.6 L
Volume of the U.S pint = 0.4732 L
therefore,
Number of pint in the container = 
= 
= 159.76
Also it is given that
Number of Pacific oysters per pint = 10
Number of Atlantic oysters per pint = 32
Thus,
for 159.76 pint
Pacific oysters in container = 10 × 159.76 = 1597.6 ≈ 1598
Atlantic oysters in the container = 32 × 159.76 = 5112.42 ≈ 5113
hence,
order short of your anticipated count = 5113 - 1598 = 3515
