oh, come on !
you never had and solved the situation "one piece costs that much, how much will be 2 or 5 or 10 of them ?"
it is a simple multiplication.
and hence the answer B.
the first hint is already in the table with 1 pizza costing $5.25.
2 pizzas are then 2×$5.25, 3 pizzas 3×$5.25, ...
so, the cost c = number of pizzas × $5.25
or short
c = p×5.25 or 5.25p

the domain is the interval or set of valid values for the input variable (x) of a function/relation.
and the range is the interval or set of valid values for the result variable (y) of a function/relation.
so, the domain is the set {-3, -1, 0, 1, 3}.
and the range is the set {-4, 0, 2, 4}.
In mathematics, a function is a binary relation between two intervals or sets that associates each element of the first interval/set (domain) to exactly one element of the second interval/set (range).
and that's what is done here.
it is a function.
each value of x is associated exactly with 1 result value of y.
a y value can be associated with more than one x value - no problem.
but no x value can have more than one associated y value - otherwise that would break the principle of a function.

Part A: Solve −mk − 90 > 85 for m. Show your work. (4 points) Part B: Solve 3c − 5f = 55 for f. Show your work. (6 points) (10 points)
Answers
Answer:
m < -175/k
f = -11 + [tex]\frac{3}{5}[/tex]c
Step-by-step explanation:
Part A:
-mk - 90 > 85
add 90 to each side to get:
-mk > 175
divide each side by -k to get:
m < -175/k
(inequality symbol switched because we divided by a negative)
Part B:
3c - 5f = 55
subtract 3c from each side to get:
-5f = 55 - 3c
divide each side by -5 to get:
f = -(55 - 3c) / 5 or -11 + [tex]\frac{3}{5}[/tex]c

where a and b are the lengths of the sides opposite the corresponding angles. From the given diagram, we can see that
[tex]\dfrac{\sin A}{7\:\text{yd}} = \dfrac{\sin 75°}{28\:\text{yd}}[/tex]
or
[tex]\sin A = \dfrac{7}{28}\sin 75° = 0.241[/tex]
