Step-by-step explanation:
Write and solve an equation of ratios to answer this question:
2 cm 3 m
--------- = ---------
7 cm L
Solve this for L by inverting both sides:
7cm L
---------- = --------
2 cm 3 m
and then multiplying both sides by 3m:
21
----- = L
2
The actual length of the wall is 10.5 m

4x - 4 = 20
4x = 24
x = 6
This is the concept of commercial arithmetic, we are required to calculate the amount that Kerri contributes towards her health insurance if the total annual contribution is $6,486 and the employer pays 80% of this;
percentage insurance that Kerri pays is:
1000-80
=20%
Annual premium= $6,486
Amount paid by Kerri will be:
20/100*[total amount paid]
20/100*6,486
=$1,297.2
The answer is $ 1,297.2
