Answers
Answer: A) 2K+2, B) 6, C) Andy spends = 360p and Laura pays = 480p
Step-by-step explanation: Andy buys K packets of crisps
Laura buys two more packets of crisps than Andy = K+2
Therefore,
The total number of packets = K+(K+2)
= K+K+2
= 2K+2
2K+2 = 14
2K = 14-2
2K = 12
K = 12/2
K = 6
Therefore, Andy had bought 6 Packets
Number of packets Andy bought = 6
Number of Packets Laura bought = 6+2 = 8
Cost of each packet = 60p
Therefore,
Andy pays = 6*60p = 360p
Laura pays = 8*60p = 480p
Answer:
Step-by-step explanation:
Packets of crips brought by Andy= K
Packets of crips brought by Laura= K+2
a) Total = K+(K+2)
b) Total = 14 packets
2K + 2 = 14
2K = 14-2
2K= 12
K= 12/2
K=6 Hence Andy brought 6 packets
c) Each packet price = 60p
Amt. Andy paid = 6*60p
= 360p
Amt. Laura paid = 6+2
= 8
= 8*60p
= 480p
