 Tomato juice, 48 oz. can for $ 2.49.
 The unit price is:
 (2.49) / (48) = 0.05 cents per oz.
 Option B:
 Tomato juice, 6-pack of 10 oz. cans for $ 3.99.
 The unit price is:
 (3.99) / (6 * 10) = 0.07 cents per oz.
 Answer:
 
The best buy would be:

The given quadratic equation gives the parameters of the shape of the

graph of the equation.

  • The graph that is most likely associated with the model is; <u>graph B</u>

Reasons:

The given function is <u>n(t) = -2.82·t² + 25.74·t + 60.87</u>

by analyzing the above function, we have;

At t = 0

n(0) = -2.82 × 0² + 25.74 × 0 + 60.87 = 60.87

  • The x-coordinate of the maximum point is given by \displaystyle x = -\frac{b}{2 \cdot a}

Which gives;

\displaystyle t = -\frac{25.74}{2 \times (-2.82)} \approx 4.564

The maximum value of the function is therefore;

n(4.564) = -2.82 × 4.564² + 25.74 × 4.564 + 60.87 ≈ 119.61

The characteristics of the equation are;

Initial value of equation = 60.87

t-coordinate of the maximum point, t ≈ 4.564

Maximum value of the of the function = 119.61

By comparing with the given graphs, we have;

  • \begin{tabular}{c|c|c|}&Graph A&Graph B\\Initial value&100&75\\t-value at max point&7&4\\Maximum value&200&125\end{array}\right]

Therefore, the graph that will most likely be associated with the model is; <u>graph </u><u><em>B</em></u>.
