Let
m-------> the cost of one meals in dollars
we know that
[tex]2m+4=16[/tex] ------> equation A
Solve for m
Subtract [tex]4[/tex] both sides
[tex]2m+4-4=16-4[/tex]
[tex]2m=12[/tex]
Divide by [tex]2[/tex] both sides
[tex]m=12/2=\$6[/tex]
the cost of each meal is [tex]\$6[/tex]
therefore
the answer is
The equation that could be used to represent this situation is
[tex]2m+4=16[/tex]
