J.100

Answer 4

I put J from the way i worked it

Answer 5

ok - how did you work this out?

Answer 6

I just want to check if you are using the right approach

Answer 7

alrighty

Answer 8

well to find an approximate guess on how many cakes were gonna be sold on the 5th friday i added all the other weeks: 15+20+18+24=77. then i found the average which was 19. so then i added 19 to the other weeks: 15+20+18+24+19=96. and the question wanted an estimate and the closest cumber on the choices to 96

Answer 9

is 100

Answer 10

yup that is fine. you could also just multiply the average by 5.

Answer 11

yes but it wouldnt be accurate

Answer 12

since the average gives you "the average number sold per week"

Answer 28

yes but im still confused!

Answer 29

take a large value for x, say x=20 and see what each of the equations give you

Answer 30

?

Answer 31

as x becomes larger and larger, which one of these do you think will increase by the most amount?

Answer 32

i thought B?

Answer 33

the key here is "grow by the most amount" - which is not the same as "have the largest value"
