She will reach her goal during week 7 with 205 minutes working out. I got this by figuring out the pattern- Week 1 to week 2: +10
                          Week 2 to week 3: +15
                          Week 3 to week 4: +20
So, I came to realize that it was adding 5, so I just added until I got past 200 minutes. 115+25= 140+30= 170+ 35=  205!!!
