Manuel needs to read 6 novels each month. Let N be the number of novels Manuel needs to read in M months. Write an equation relating N to M . Then use this equation to find the number of novels Manuel needs to read in 13 months.

Each month Manuel reads 6 novels so you get
[tex]n = 6m[/tex]
If you plug in 13 for m we get
[tex]n = 6(13) = 78[/tex]
Manuel needs to read 78 novels in 13 months.
