The number is negative 23
Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
Answer
Helena could bake:
2 loaves of bread
4 batches of muffins
For a customer to choose a chocolate cone it need to choose "Chocolate" (0.35 probability) and choose a cone (0.4 probability given he chose chocolate).
So, the get the probability of both, we multiply their probabilities:
Thus, the probability of a customer choosing a chocolate cone is, based on the image, 0.14 or 14%.
