<span>When we make a family tree, we make a chart of the people that came before us. They're called family trees because they tend to branch out as they progress, as each ancestor gives way to more ancestors. In the same way, a factor tree shows the numbers that come together to create a larger number, and it branches out as it progresses because each resulting factor then gives way to its own factors. In other words, a factor tree is a tool that breaks down any number into its prime factors.</span><span>Before we go into detail about factor trees, we need to review factors. Factors are simply numbers you can multiply together to get a certain product. For example, if we're looking at 2 * 3 = 6, then 2 and 3 are factors of 6. But, we could also say that 1 * 6 = 6. So, 6 has four factors: 1, 2, 3, and 6. This factor business could get messy with large numbers because, generally speaking, the larger a number is the more factors it will have. That's where the factor tree comes in. maybe that can help you</span>
Answer:
$3000 was invested at 11%.
Step-by-step explanation:
The total interest was $426. This was comprised of interest earned at 8% (represented by e) and (separately) interest earned at 11% (represented by v).
Then e + v = $4200 total investment, and
i = $426 = e(0.08)(1 year) + v(0.11)(1 year)
We eliminate the variable e as follows: since e + v = $4200, e = $4200 - v. Thus,
i = $426 = e(0.08)(1 year) + v(0.11)(1 year) becomes:
i = $426 = ($4200 - v)(0.08)(1 year) + v(0.11)(1 year)
This is one equation in one unknown, the amount of $ invested at 11%.
Performing the indicated multiplications:
426 = 4200(0.08) - 0.08v + 0.11v. Simplifying this further, we get:
426 = 336 + 0.03v.
Then 90 = 0.03v, and v = 90 / 0.03 = $3000.
$3000 was invested at 11%.
