For question a) you can do 2 x 7 sine their are 7 days in a week 2 x 7 = 19 so by the end of each week Carmen has $19. in 10 weeks she will have $20 dollars. if in 10 weeks she has $20 wait if it is time two there can't be 35 try 17 cause that's closes so in 17 she will have $36. Same thing Lilly starts with $10 each week she gets $1 a week so 1 x 7 = 7 and since she started with $ 10 she has $17 Lilly must earn 19 dollars to be equal with Carmen. Hope this helps
