Question

please help im tierd of posting and getting no response will fan and medal...Eva makes a few dozen cupcakes and sells them for $8 a dozen. Which function represents the relationship between the money Eva earns, m, and the number of cupcakes she sells, c?
f(c) = c × 8
f(m) = c × 8
f(c) = m × 8
f(m) = m × 8
f(m) = c × m

Answer 1

Okay she earns money for each cupcake she sells right?

Answer 2

yeah

Answer 3

which means the more cupcake she sells the more money she earns right?

Answer 4

yeah

Answer 5

so we can make an equation money = k* cupcake, right?

Answer 6

where k is just a constant

Answer 7

where do u get k?

Answer 8

i see m c and f

Answer 9

that is just a constant. Like 1,2 or 3

Answer 10

I will get to it, but just answer my question now?

Answer 11

im still confused but ok

Answer 12

the money Eva earns, m, and the number of cupcakes she sells, c?

Answer 13

And each dozen of cupcake is worth 8 dollars so m = 8c, right?

Answer 14

see we know this but how do i find out the equation

Answer 15

yes

Answer 16

Okay each dozen of cupcake is worth 8 dollars. So if she sell each dozen of cupcake she gets 8 dollars. She sells two, she gets 16 dollars.
From this we can see, money = 8 * cupcake

Answer 17

f(c) = c × 8
f(m) = c × 8
f(c) = m × 8
f(m) = m × 8
f(m) = c × m

Answer 18

how do we get these equations from that tho???

Answer 19

oh i get it so would it be the second 1?

Answer 20

yes

Answer 21

ok thanks man u have no idea how annoying it gets posting all these questions and ur the first to give me a response all day
