Step-by-step explanation:
I don't know if you do this the same way I did, but..
The first step is to subtract 9 on both sides, like this.
13w + 9 = 178
-9 -9
You'll end up with:
13w = 169
I don't know if you need the answer or not but I'll help you out.
For the second step, divide both sides by 13w.
13w = 169
/13w /13w
w = 13
Hope this helped!
Answer: her interest in 3 years is $45
Step-by-step explanation:
For simple interest, the principal is not compounded. The interest is only on the original capital. The formula for simple interest is expressed as
I = PRT/100
Where
I represents the interest on the principal
P represents the initial amount
R represents the interest rate.
T represents the time in years.
From the information given
P = $300
R = 5%
T = 3 years
I = 300×5×3)/100
I = 4500/100 = 45
The answer is <u>y</u><u>=</u><u>|</u><u>x</u><u>|</u><u>-13</u>.
