Answer:
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
