Answer: 2.09
Step-by-step explanation:

For proportions and to find x we have to cross multiply
8 × (x) = 3 × 2.4
8x = 7.2
Divide by 8 to isolate x

8 and 8 cancels out
x = 0.9
Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 8 months = 8/12 = 2/3 years
P = $3000
R = 9.3%
Therefore
I = (3000 × 9.3 × 2/3)/100
I = 18600/100
I = $186
The maturity value (in dollars) of this loan would be
3000 + 186 = $3186

Step-by-step explanation:
4(3+1)+2 = 18
(4+2)(3)+1 = 19
(1)(2+3)(4) = 20
(1+2)(3+4) = 21
