Answer:
2.5 years
Step-by-step explanation:
Given data
Principal= Rs 24000
Final amount A= Rs 30000
Rate r= 10%
The simple interest expression is
A=P(1+rt)
substitute
30000=24000(1+0.1*r)
30000=24000+2400t
30000-24000=2400t
6000=2400t
t= 6000/2400
t=2.5
Hence the time is 2.5 years
Solution:
We are given that lena sells cosmetics and recieves commissions of 45%.
She sold $200 worth of cosmetics to one customer.
It mean she will get a commission of 45% on $200. So we will find 45% of 200 and the resulting value will be the comission of Lens.
45% of 200
Comission recieved
It mean that when leena sells cosmetics of $200, she gets a comission of $90.
38 because you take the area A and divide it by the base B and you get your answer for height H. H=A/B or A=HB.
(x*2 + 11x)+ 24
half of 11 is 5.5*2
(x*2+ 11x + 30.25 ) + 24 -30.25
(x*2 + 11x) -6.25
so
Vertex (11,-6.25)
