Step-by-step explanation:
Let the total number of pencils that Jackson has be represented by x.
Since 20% of his pencils are broken which equals 4. This can be written and represented in an equation as:
20% of x = 4
20/100 × x = 4
0.2x = 4
x = 4/0.2
x = 20
There are a total of 20 pencils

Answer:
3.5 years.
Step-by-step explanation:
The formula for depreciation is as follows (I had to look it up too):
worth after time = initial worth * (rate)^t
In this case it depreciates which means that the rate is 1-0.18 = 0.82.
we know it will be worth 15,000,
So substituting would give us

now we we need to solve for t, so we will end up with
1/2 = 0.82^t
log (1/2) = t log(0.82)
t = 
Therefore, t is roughly 3.5 years.
Great question, hope this helps.
