Answer:

C) 0.42 + 0.17 | w: $1.10

Step-by-step explanation:

Note that amount of ounces is denoted by the variable "w". The cost per ounce is $0.17, while the constant charge (charge doesn't change per ounce) is $0.42.

Set the equation:

(Cost per ounce x Amount of ounces) + Constant charge = Total charge:

(0.17x) + 0.42 = Total Charge

Total Charge = 0.17x + 0.42

Next, you are solving for the cost of 4 ounces. Plug in 4 in the variable, x.

Total Charge = 0.17x + 0.42

                      Plug in 4 for x.

                      = 0.17(4) + 0.42

                      Follow PEMDAS, First, multiply, then add:

                      = (0.17 * 4) + 0.42

                      = 0.68 + 0.42

                      = 1.10

~

C) 0.42 + 0.17  | w: $1.10 is your answer.
