For better representation, I think the function is written as:
B(x) = 40.00 - 0.08x
This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.
B = 40 - 0.08(40)
<em>B = $36.8</em>
Answer: Look at my attached example.
Hopefully this helps with converting units.
All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)
The expression consists of 4 terms, and each term contains 2 factors.
1) In this expression:
ab +cd + ef +gh
We can make the following definitions:
2) Factors are numbers or letters (in algebra) that we can use to multiply themselves and yields another number.
Terms can be defined as letters, numbers within an expression.
3) Hence, In this expression, we have then:
4 terms: ab, cd, ef, and gh
2 factors per term.
The expression consists of 4 terms, and each term contains 2 factors.
