Answer:
Step-by-step explanation:
It is given that, 
We need to find the value of 
As 
Solving LHS

Now comparing the coefficients of 
In LHS the coefficient of
is 25
In RHS the coefficient of
is 
It implies that, 
So, the value of
is 25.
Answer:
see the explanation
Step-by-step explanation:
In this problem
I will assume that the total amount required for the trip is $1,200
so
Let
x ----> the number of weeks
we know that
The number of weeks multiplied by $75 plus $300 must be at least $1,200
In this context, the term "at least" means "greater than or equal to"
so
The linear inequality that represent this problem is

Solve for x
subtract 300 both sides


Divide by 75 both sides

therefore
The minimum number of weeks you need to save is 12
