The system of equations to consider would include: p + m = 19 and 0.25p + 0.75m = 11.50. To establish this system, first define the total amount bought with the initial equation where p signifies pens and m denotes markers. The subsequent equation will utilize cost alongside the total expenditure.
Answer:
The cost difference per mile between the two companies is $0.12.
Step-by-step explanation:
Gabi formulates the equation
to determine after how many miles, denoted as m, the charges of both companies will be equal.
The first company levies
for m miles traveled.
The second company's charge for the same m miles is
.
In these equations, the figures 7.20 and 8.40 signify the initial fees the companies impose.
The values 0.22 and 0.1 represent the respective costs per mile.
As such, the disparity in per-mile charges amounts to
.
An alternative method to tackle this problem is by calculating the per-mile rate for each company:
1. Cost per mile for the first company

2. Cost per mile for the second company

3. The difference:

Answer:

Step-by-step explanation:
The equation provided is:
d = 5x + 10xf
We need to isolate x from this equation.
Factoring out x from the right side gives us,
d=x(5+10f)
To find x, divide both sides by (5+10f),

Thus, this represents the sought value for x.
