Step-by-step explanation:
If a quadratic trinomial has a leading coefficient of 1 and a positive constant, then it is very easy to factor.
You just have to look for two factors of the constant term that add up to the coefficient of x( the middle term).
Then you write as factors.
For instance;

To factors of 6 that add up to 5 are 2 and 3.
Therefore the factorization is:

Answer:
$3.7625
Step-by-step explanation: I may be wrong but...
If you find 75% of $2.15 it is equal to $1.6125.
Since in "increases" we are going to add $1.6125 to $2.15.
You get the answer of $3.7625.
