Answer:
y = 5x
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition that y = 30 when x = 6
k = 
= 
= 5
y = 5x ← equation of proportion
Using proportions, it is found that the children made 408 snowflakes on the third day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
On the first day, they made 30% of the total amount of 1,200, hence:
D1 = 0.3 x 1200 = 360
On the second day, they made 20% more day in the first, hence:
D2 = 1.2 x 360 = 432.
On the third day, they made the remaining amount, hence:
D3 = 1200 - (360 + 432) = 408.
