Question

lets say i have 21$, and i want to buy some flowers for a friend. roses are 3$ each and daisies are 2$ each. i buy three more daisies then i do roses. how much did the roses cost?

Answer 1

Let d = # of daisies
Let r = # roses

Can you write a relationship using d and r that relates the two quantities in such a way that you "buy three more daisies then you do roses" ?

Answer 2

i think so....

Answer 3

If you buy 1 rose, how many daisies did you buy?

If you buy 2 roses, how many daisies did you buy?

If you buy r roses, how many daisies did you buy?

Answer 4

ty

Answer 5

Do you understand what to do next?

Answer 6

And I think you want to know how many roses you bought, not how much they cost because the problem tells you how much the roses cost.

Answer 7

i thought that to, but it is cost.

Answer 8

Well, to get that you need to know how many you bought in total so you can take that number multiplied by $3 each to get how much the roses cost.

Answer 9

thanks bro

Answer 10

Let me know what answer you get so I can check to make sure you got it right. :)

Answer 11

lol
ok

Answer 12

the roses cost 9$....?

Answer 13

Yes. That's right. You buy 3 roses for $3 each = $9.

Answer 14

You can check to make sure this makes sense.

If you buy 3 roses, then you buy 3 + 3 daisies = 6 daisies.

3 roses cost $3 = $9 and 6 daisies cost $2 = $12

$9 + $12 = $21 which is what you spent in total.

Great work.
