Both of them are the first answer choice
Answer:
!. Scale factor = 5
2. Scale factor = 
Step-by-step explanation:
scale = 
1. To increase the numbers, let the scale factor be
= 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be
. So that;
0.05 x
= 0.01
x
= 0.5 x
= 0.10
7 x
= 1.40
13 x
= 2.60
25 x
= 5.00
102 x
= 20.40
The formula of compound continuously is
A=p e^rt
A future value?
P present value 300
R interest rate 0.07
T 4 years
E constant
A=300×e^(0.07×4)
A=396.94 round your answer to get
A=397
