Answer:
depending theres 10 and 9 and 8
Explanation:
if she wants to get 40 its 8 because 40÷5=8 and if she can do 5 but wants to get up to 50 she will have to do 9 weeks because 50÷5-5=5 so you take 5 and subtract it by 50 and you get 45 and what times 5 gets you 45 it gets you 9 so basically 9 weeks to get to 50 if she can already do 5 and if she wants to get up to 50 from 0 its 10 weeks hope this helps
