Answer:
For one month:22*.025=.55
For 6 moths: 6*.55 =3.3
The answer is 3.3 $
1/4(2x-14)=4
2x/4-14/4
X/2-7/2=4
x-7/2=4
8=x-7
8+7=x
X=15
Divide both sides by 3.1 and find g = 20.9/3.1 ≈ 6.7 ≈ 7.
You can estimate this without a calculator by saying 20.9 ≈ 21 and 3.1≈3, then 21/3=7.
In general, be careful with rounding before a calculation, because the rounding errors can be enlarged, messing up the accuracy of your answer. It's best to round only at the end.
