Answer:
principal=32000
Step-by-step explanation:
I=p×r×t/100
6400=p×4×5/100
640000=p×20
p=32000
Answer:
20% increase
Step-by-step explanation:
To find the percent increase, divide the difference in the number of bracelets by the original number:
2/10
= 0.2
So, the percent increase was 20%
Answer:
D
Step-by-step explanation:
x² - 81 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Here a = x and b = 9, thus
x² - 81 = (x + 9)(x - 9) → D
Answer:
Option C
Step-by-step explanation:
Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,
P ∝ N
P = kN
Here 'k' is the proportionality constant
To get the value of proportionality constant,
Since, value of 10 cribs is $1320
1320 = k(10)
k = 132
Therefore, equation will be
P = 132N
Option A
If number of cribs = 6
P = 132(6) = $792
False.
Option B
For N = 22
P = 132(22) = $2904
False.
Option C
For N = 40
P = 132(40) = $5280
True
Option D
For N = 55
P = 132(55) = $7260
False
Option E
For N = 80
P = 132(80)
= $10560
False
Option F
For N = 250
P = 132(250)
= $33000
False
If the given options have been written correctly only one option, Option (C) is correct.
