Using a proportional relationship, we have that:
The cost of a 6-mile ride during high-demand hours is $21.56.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the function is:
f(x) = 2.30x.
The cost for 6 miles is:
f(6) = 2.30 x 6 = $13.8.
5 plus 120% of that is:
1.2 x 13.8 + 5 = $21.56.
The cost of a 6-mile ride during high-demand hours is $21.56.

This is standard form 10,000+5,000+400+9
1 yd equals 3 feet
multiply 3 to the 33 yards to find the feet
33 x 3 = 99
33 yards = 99 feet

Answer: -13 °C.
Step-by-step explanation:
Let's call the number of blue and black pens, respectively, and . We know that there are 29 pens in total, and no other colors. This means that
i.e. the number of blue and black pens, together, must add up to 29.
Now, we also know that there are 3 more blue than black, which in other words means that the number of blue exceeds the number of black by 3:
We can use this expression to substitute in the first equation:
So, there are 13 black pens. Since the blue are three more than the black, Suzie has 16 blue pens.
