Let's denote the number of seashells that Lucy has as \( L \). According to the problem, Daisy has 6 more than three times the number of seashells Lucy has. This can be expressed in the equation:
\[ D = 3L + 6 \]
We know that Daisy has 36 seashells, so we set \( D = 36 \):
\[ 36 = 3L + 6 \]
Now, we can solve for \( L \):
-
Subtract 6 from both sides of the equation: \[ 36 - 6 = 3L \] \[ 30 = 3L \]
-
Divide both sides by 3: \[ L = \frac{30}{3} = 10 \]
Therefore, Lucy has 10 seashells. The correct response is:
