    430p

    Step-by-step explanation:

    For this, we'll find the least common multiple for 15 and 18.

    => The least common multiple for 15 and 18 is 90

    Plastic Knives:

    Jace will buy 90 knives.

    => Packets = 90/18 = 5 Packets

    Money for 5 Packets = 5 * 45

    => 225p

    Plastic Forks:

    Jace will buy 90 forks also.

    => Packets = 90/15 = 6 Packets

    Money fro 6 packets = 6 * 41

    => 205p

    Least Amount of Money Jace will spend = 225p+205p

    => 430p
