Answer:
The average selling price of each trailer was nearly $922
Step-by-step explanation:
University trailer sales company sold 356 utility trailers during a recent year.
If the gross annual sales for the company was $328,132.
For the average selling price of each trailer, we will divide <em>the gross annual sales </em>by <em>utility </em><em>trailers.</em>
= 328132 ÷ 356
= 921.7 ≈ 922
Thus, The average selling price of each trailer was nearly $922

Answer:
A equação da reta é dada por: 
Step-by-step explanation:
Equação de uma reta:
A equação de uma reta tem o seguinte formato:

Em que a é o coeficiente angular e b é o coeficiente linear.
Coeficiente angular:
Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.
A(-1, -2) e B(5,2)
Mudança em y: 2 - (-2) = 2 + 2 = 4
Mudança em x: 5 - (-1) = 5 + 1 = 6
Coeficiente angular: 
Então:

Coeficiente linear:
Substituindo um ponto na equação, encontra-se o coeficiente linear.
B(5,2)
Quando
. Então:

The problem describes a function that expresses the concentration of an antibiotic in mg/dl vs time in hours as:

We need to find the first value of t such that

It means that

Operating with the inequality

Rearranging and dividing by 2, we have a polynomial inequality:

Factoring

There are two possible values for t, both valids because they are positive

We need to find the first value, i.e.

Now for the graphic method, we plot the graph for the function and a horizontal line at c=4 to find the values of t.
The graph is shown in the image provided below. We can see both values where the funcion and C=4 intersect. Both values coincide with the previously analitically found values
Answer:
Therefore, x = -2m+4/-n-1
What I got is this: 15% of $48.32 = $7.25
