Answer:
$216435
Step-by-step explanation:
Given : Suppose homes in a big city increase in value 13% every year.
To Find: How much will a home that cost $150,000 be worth 3 years later?
Solution:
Principal = $150000
Rate = 13% =0.13
Time = 3 years
Formula :
Now substitute the values in the formula
So, The cost of home after 3 years will be $216435
Hence Option B is true
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
BB' = 6
B'A = 2
Step 02:
scale factor:
The answer is:
scale factor = 3
Keep in mind that you can gather only like terms. Two terms can be summed/subtracted if they involve the same powers of the same variables.
So, going point by point:
- We can subtract the terms, because they both involve the variable
, and we have
- We can sum the terms, because they all involve the variable
, and we have
- We can't sum this terms: 3 is a pure number, while 3r involves the variable r.
- We can only sum the two terms: we have
- We can't sum this terms: -20 is a pure number, while -15p involves the variable p.
- We can sum the terms, because they all involve the variable
, and we have
