Question

3) gentry is training for a marathon. she increases the amount of time she runs by 5 mins. each day to build up her endurance. on the first day, she runs for 30 minutes. how many minutes does she run on day 5?

A) 35 mins
B)45 mins
C)50 mins
D)150 mins

Answer 1

y=5x+30

X is the days

And so by plugging in x you get

y=5(5)+30
y=25+30
y=55

And so by day 5 she's running 55 minutes

But that's what I think
