Answer:
48
Step-by-step explanation:
Let the total number of truffles be represented by y
Leanne collected 1/4 of the truffles, hence remaining truffle is
1 - 1/4 = 3/4
Jeff collected 1/2 of remaining truffles implying that Jeff collected
3/4 x 1/2 = 3/8 of the truffles
the remaining truffle is
3/4 - 3/8 = 3/8
since truffles left are 18
(3/8)*y = 18
y = 18 x 8 / 3
y = 48
hence total number of chocolate truffles is 48
