Let the number of cards equal x.
Set up an equation for both companies, set equal to each other and solve for x.
0.10x + 12 = 0.12x + 10
Subtractb0.10x from both sides:
12 = 0.02x + 10
Subtract 10 from both sides:
2 = 0.02x
Divide both sides by 0.02:
X = 2/0.02
X = 100
100 cards would be the same price for both companies.
Answer:
3. positive correlation but not causal relationship
Step-by-step explanation:
A positive correlation is when one factor increases, the other factor increases as well.
A negative correlation is when one factor increases, the other factor decreases.
A causal relationship is when one factor <em>causes </em>the other factor change in a certain way (i.e. increase or decrease).
More people buy ice cream as the day becomes hotter and sunnier. This also applies to people choosing to wear sunglasses. Therefore, there is a positive correlation between the two (because both increase). However, this is not a causal relationship because the cause of both is the hotter and sunnier day.

Given:
The pie chart shows the flavours of ice cream sold by a shop in one day.
There were a total of 270 ice creams sold.
To find:
The number of vanilla flavoured ice creams sold.
Solution:
We know that the complete central angle is 360 degrees.
From the given pie chart, it is clear that the central angle of the vanilla flavoured ice creams sold is 60 degrees.
Total ice creams sold = 270
Now, the number of vanilla flavoured ice creams sold is

Therefore, the number of vanilla flavoured ice creams sold is 45.
