Question

4) The cost C, in dollars, for Domino's Pizza delivered depends on the number p, of pizzas ordered.

This situation is represented by the function rule C = 7p+3.
a) Complete the table below.

Answer 1

Answer/Step-by-step explanation:

Function rule is given as C = 7p + 3

To complete the table, substitute each value of p given and find C.

✔️Number of pizza (p) = 0 [first row]:

Substitute 0 for p into C = 7p + 3

C = 7(0) + 3 = 0 + 3

Cost ($) (C) = 3

(p, C) order pairs = (0, 3)

✔️Number of pizza (p) = 1 [second row]:

Substitute 1 for p into C = 7p + 3

C = 7(1) + 3 = 7 + 3

Cost ($) (C) = 10

(p, C) order pairs = (1, 10)

✔️Number of pizza (p) = 2 [first row]:

Substitute 2 for p into C = 7p + 3

C = 7(2) + 3 = 14 + 3

Cost ($) (C) = 17

(p, C) order pairs = (2, 17)

✔️Number of pizza (p) = 3 [first row]:

Substitute 3 for p into C = 7p + 3

C = 7(3) + 3 = 21 + 3

Cost ($) (C) = 24

(p, C) order pairs = (3, 24)
