Alicia borrowed 15,000 to buy a car. She borrowed the money at 8% for 6 years. How much will she have to pay the bank at the end
Leya [2.2K]

Hello,

Alicia borrowed $15,000

At 8% for 6 years

To get the % for 1 year

First multiply 15,000 by 8% (On a calculator would be easier)

You get 1,200

Now since she borrowed the money for 6 years, multiply 1,200 and 6

You get $7,200

So now, you add the $15,000 and $7,200

So Alicia has to pay $22,200 at the end of 6 years

Hope this helps

I have this question that i dont get plz help-2|2.2x-3.3|=-6.6
maria [59]

Step-by-step explanation:

Absolute value of a number gives the positive quantity of the number.

For instance,

|3|=3, |-3|=3

From this example, therefore we know that

\text{If }|x|=a,\text{ then }x=a\text{ or } -a.

--------------------------------------------

In this question,

-2|2.2x-3.3|=-6.6

|2.2x-3.3|=3.3

2.2x-3.3=3.3\text{ or } -3.3

2.2x=3.3+3.3 \text{ or }-3.3+3.3

2.2x=6.6\text{ or } 0

x=3\text{ or } 0
