add the like terms that are on the left, then isolate the variable (a) on the left by dividing both sides by .

2a + 6a = -24

8a = -24 <em>added like terms (2a + 6a)</em>

8a/8 = -24/8 <em>divided both sides by 8</em>

a = -3 <em>simplified (8/8 = 1 and -24/8 = -3)</em>

Answer: -3

I wish to have $10,000 at the end of 8 yers in a bank offering a simple interest rate of 7.5% per year. How much should I deposi

kolezko [41]

Answer:

You have to invest $6,250

Step-by-step explanation:

very simple applying the simple interest formula which is

$A = P (1 + rt)$

Given data

A, final amount = $10,000

P, initial principal balance= ?

r, annual interest rate = 7.5%

t, time (in years)= 8 years

we can substitute our given data to find the principal needed.

$10000= P(1+0.075*8)\\\10000= P(1.6)\\\$

Divide both sides by 1.6 we have

$P= \frac{10000}{1.6} \\\P= 6250$

P= $6,250
