Solve a(3 x-2b)=c(2x-2) for x

1 answer:

6 0

A(3 + x - 2b) = c(2x - 2)
3a + ax - 2ab = 2cx - 2c
2cx - ax = 3a - 2ab + 2c
x(2c - a) = 3a - 2ab + 2c
x = (3a - 2ab + 2c)/(2c - a)

Marrrta [24]

Answer:

$\$522.78$

Step-by-step explanation:

Let

x ---> the number of years

y ---> the amount in the account balance

Plan A

we have a linear equation of the form

$y=mx+b$

where

The slope is equal to

$m=\$100\ per\ year$

The y-intercept or initial value is

$b=\$500$

substitute

$y=100x+500$

For x=10 years

substitute

$y=100(10)+500=\$1,500$

Plan B

we have a exponential growth function of the form

$y=a(1+r)^x$

where

$a=\$500\\r=15\%=15/100=0.15$

substitute

$y=500(1+0.15)^x$

$y=500(1.15)^x$

For x=10 years

substitute

$y=500(1.15)^{10}=\$2,022.78$

Find the difference of the two account balances after 10 years

$\$2,022.78-\$1,500=\$522.78$
