Answer:
Demand quantity: 6.3246
Supply quantity: 4.4721
Step-by-step explanation:
Supply equation:
p = (1/2) * q^2
Demand equation:
p = -(1/2) * q^2 + 30
(p is the price, q is the quantity)
If the price p is equal to 10, then we can calculate:
Supply quantity:
10 = 0.5 * q^2
q^2 = 20
q = 4.4721
Demand quantity:
10 = -0.5 * q^2 + 30
0.5 * q^2 = 20
q^2 = 40
q = 6.3246
Answer:
1668.75
Step-by-step explanation:
75,000 is what i think the answer is because i know what it is.
4) 41% of 78 is what?
Answer = 31.98
Work:
x = 41/100 x 78
x = 3198/100
x = 31.98
6) 58% of what is 63.4?
The number is = 109.31
Explanation:
Let the number be = x
58/100 (x) = 63.4
x = 63.4 x (100/58)
x = 6340/58
x = 109.31
