Respuesta :

we can write an equation

[tex]V=4t+12[/tex]

where V is the volume and t the time on minutes

we can repalce the value of t to find v

t=1

[tex]\begin{gathered} V=4(1)+12 \\ V=16 \end{gathered}[/tex]

t=2

[tex]\begin{gathered} V=4(2)+12 \\ V=20 \end{gathered}[/tex]

t=3

[tex]\begin{gathered} V=4(3)+12 \\ V=24 \end{gathered}[/tex]

t=4

[tex]\begin{gathered} V=4(4)+12 \\ V=28 \end{gathered}[/tex]

t=5

[tex]\begin{gathered} V=4(5)+12 \\ V=32 \end{gathered}[/tex]
