Answer:
2k + 2
Step-by-step explanation:
It's said that Andy buys k packets of crisps, meaning this is an unknown variable. Since Laura buys two MORE bags of crisps than Andy, her total number of chips will be k + 2. To find the TOTAL number of crisps between the two of them, you would have to add Andy's crisps, k, to Laura's crisps, k + 2. This will give you k + k + 2, which is just 2k +2.
