Question

Christa buys 14 flowerpots. Some are small and cost $2.40 each. The rest are large and cost $5.60 each. She spends a total of $49.60.



Which equation models this situation?



Let s represent the number of small flowerpots she buys.


A.


5.6s + 2.4(s + 14) = 49.6


B.


(2.4 + 9.6)(14 – s) = 49.6


C.


2.4s + 5.6(14 – s) = 49.6


D.


5.6s + 2.8(14) = 49.6

Answer 1

let the number of small flowerpots bought = s, then the number of large pots bought is (14 - s)

This should help.

Answer 2

So the money spent on small pots = 2.4s
Now work out the money spent on large pots in terms of s.
Then add these 2 costs togther and they equal $49.60

Answer 3

Thank you very much @welshfella

Answer 4

Answer 5

So it would be B?

Answer 6

No
work out how much money he spends on large pots
= (14 - s) times 5.60.
this is added to 2.4 s

Answer 7

So it would be C

Answer 8

yes
2.4s + 5.6(14 - s) = 49.60
