Extra large candies
Step-by-step explanation:
Let small candies
Extra large candies
the number of candies is at least .
Cost of small candy
Cost of extra large candy
but she has only to spend
Solve for
Since number of candies should be integer.
let
total spend which is more than
, so this combination is not possible.
She has more so she can buy
more small candy.
Hence small candy

Answer:
k = 11/3
Step-by-step explanation:
If the line is tangent to the curve, then Δ = 0.
______________
Remembering:
Δ>0 two different points of intersection x' x''
Δ=0 one point of intersection x' = x''
Δ<0 two different points of intersection in the complex plan x' and -x'
______________
As the line and the curve have one point of intersection, which is (x, y), we can make a equality between them:
2x + k = 3x² + 4
0 = 3x² - 2x + (4 - k)
Now we can use the Δ=0 (Δ= b² - 4ac)
Δ = 0 = (-2)² - 4.3.(4-k)
0 = 4 - 48 + 12k
12k = 44
k = 44/12 = 2 . 22 /3. 2.2 = 22/3.2 = 11/3
k = 11/3
