Answer:
Time taken to fill 40-ounce cup, t = 0.2 x Volume of cup in ounce = 0.2 x 40 = 8 seconds
Step-by-step explanation:
A soda machine takes 3 seconds to fill a 15-ounce cup.
Time taken to fill 15-ounce cup = 3 seconds
[tex]\texttt{Time taken to fill 1-ounce cup = }\frac{3}{15}=0.2seconds[/tex]
Now we need to find equation for t which is the time to fill a 40-ounce cup.
[tex]t=\texttt{Time taken to fill 40-ounce cup}\\\\t=\texttt{Time taken to fill 1-ounce cup}\times 40\\\\t=0.2\times 40=8seconds[/tex]
Time taken to fill 40-ounce cup, t = 0.2 x Volume of cup in ounce = 0.2 x 40 = 8 seconds
