Each pound costs 2.40,
to check this 2.40 * 5 = 12
so 2.40 * 7 = 16.80
Answer: 16.80
Answer: 22.5
Step-by-step explanation:

Answer:
126 cents, or $1.26
Step-by-step explanation:
First you divide 42 by 12 and get 3.5, then you multiply that by 36 and get you answer.
Answer:
B. The maximum occurs at the function's x-intercept.
Step-by-step explanation:
Given table:

From inspection of the table, we can see that:
and
This indicates <u>symmetry</u>.
The line of symmetry is the mid-point between the two x-values.
Therefore, the <u>line of symmetry</u> is x = -4
The vertex (minima/maxima) is on the line of symmetry, therefore the vertex is at (-4, 0). As the function decreases as x → 0, the vertex is a <u>maximum</u>.
As the y-value of the vertex is 0, the maximum occurs at the function's <u>x-intercept</u>.
