Juan spent 10 minutes on his history homework and 3 minutes per question on his math homework. Which graph shows the total homework time, t, related to the number of math questions, q?

Answer 1

The total time spent on homework (t) = History time + Math Time

t = fixed amount of time spent on History (10 mins) + Variable time spent on Math (each question he spends 3 mins)

t = 10 + 3q
