A local bank in town offers two types of savings plan with different interest rates to customers. Plan A offers an annual intere

scoray [572]

Assuming he had not dealt with the bank offering plan B before, he has nothing deposited two years back. Hence plan B only gives him only 0.2% annual interest for his deposit.
Plan A gives 0.25% for his deposit all the time.
So plan A is more advantageous.

For durations,
To reach $1,000,000 from $100,000, the money needs to grow 10 fold, or
(1+i)^n=10
n=log(10)/log(1+i).

So for plan A:
n=log(10)/log(1.0025)=922.18 years, while for

plan B
n=log(10)/log(1.0020)=1152.44 years.

Hope the bank(s) still exist at that time.

Reduce to the simplest form. -9/6 + (-3/5)

creativ13 [48]

Answer:

$-\frac{21}{10}$ or $-2.1$ (they're the same)

Step-by-step explanation:

Simplify: $-\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}$
Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18
Write the new fractions: $-\frac{45}{30} - \frac{18}{30}$
Subtract: -45/30 - 18/30 = $-\frac{63}{30} = -\frac{21}{10}$

I hope this helps!
