Answer: Option 'B' is correct.
Step-by-step explanation:
Number of pounds of candy = 30
Cost per pound = $1.10
Total amount would be
Let the number of pound that sold at $1.50 per pound be 'x'.
Let the number of pound that sold at 90 cents per pound be '30-x.
According to question, we get that
Hence, there are 10 pounds of chocolates worth $1.50 per pound.
Therefore, Option 'B' is correct.
Given function :
We need to identify a " initial amount", b "growth factor", r " rate of growth".
We know, exponential growth formula
, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.
⇔
.
We can see a= 1.05 and b = 1.46.
Now, b=1+r.
Therefore, 1+r =1.46.
Subtracting 1 from both sides, we get
1+r-1 =1.46-1
r = 0.46.
On converting 0.46 into percentage, we get
0.46 × 100 = 46.
Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.
