Leto [7]

Answer:

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.

Step-by-step explanation:

Future value with annuity:

The future value formula, for an annuity, is:

$FV = \frac{P((1+r)^{n} - 1)}{r}$

An annuity means that a number of payments happen during the period(an year, for example.

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

1000 € each year, so $P = 1000$

Interest rate of 6%, so $r = 0.06$

One application per year for 8 years, so $n = 8$

Total amount:

$FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47$

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.

Gwendolyn is asked to solve the equation –4(x – 3) = 20. She shows the work below and states that the solution is x = –8. –4(x –

____ [38]

Answer:

$x=-2$

Step-by-step explanation:

Given: Equation is $-4(x-3)=20$

To find: flaw in Gwendolyn's work and the correct solution to the equation.

Solution:

In the given question,

the first step is $-4(x-3)=20$

The second step is $-4x+12=20$

(This step is obtained on multiplying $-4$ by $x-3$ )

The third step is $-4x=32$

This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:

$-4x=20-12\\-4x=8\\x=-2$

So, the correct solution is $x=-2$
