Rick has created the chart above outlining the information he has on producing toy trains. He will create a two-dimensional chart to visualize the information. Please refer to the chart above as you answer the questions below.
-Looking at the chart above, what would the mathematical formula be for required molding time?
A) Required molding time = (0.20 x (Model I quantity)) - (0.20 x (Model II quantity))
B) Required molding time = (70.0 x (Model I quantity)) + (70.0 x (Model II quantity))
C) Required molding time = (0.70 x (Model I quantity)) - (0.70 x (Model II quantity))
D) Required molding time = (0.20 x (Model I quantity)) + (0.20 x (Model II quantity))

According to the chart, the required molding time for each model is 0.20 hours per toy. Therefore, the formula for required molding time for both models would be: 
Required molding time = (0.20 x (Model I quantity)) + (0.20 x (Model II quantity)) 
This formula would give the total molding time required to produce all the toy trains, taking into account the quantity of each model.
