Question

Carmen currently has $5; she makes $2 a week in allowance. Question: a) Write a function C(x) that represents how much money she will have at the end of each week, x. b) How much money will she have in 10 weeks? c) How long until she has $35? d) Carmen's sister Lilly has $10, but only makes $1 a week in allowance. Write a function L(x) to represent how much she will have at the end of each week, x. e) How long will it take until Carmen and Lilly have the same amount of money?

Answer 1

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

Answer 2

Hey! Here r the answers I got and submitted for those same questions.

A) C(x) = 5 + 2x  

B) In ten weeks she will have $25. The function is as shown, C(10) = 5 + 2 * 10

C) Carmen will have $35 in 15 weeks.  

D) L(x) = 10 + 1x

E) In 5 weeks Carmen and Lilly will have the same amount of money; both will have $15.

(I added a bit more info on each question than was needed but the answers r in bold)
