Hi there!
Craig's reason is not reasonable because when you add fractions you have to find equivalent fractions.

Hope this helps :)

Answer:
The answer is $20.21
Step-by-step explanation:
So first you find the subtotal cost of the lunches. Each lunch costs $20, so that would be $40 in total.
Now you find the total cost.
She has to pay 5% sales tax so to find the total, you have to multiply 40 by 0.05. That gives you a total of $2. Then you add that to your $40 to get $42.
Now for the tip.
It says to find 10% of 20, so you have to multiply 20 by 0.1. That equals 0.208. Then you add that to 20 to get 20.208.
If you round off, you get a total of $20.21
Convert all to lb and find cost per 1lb
A.
54oz, convert to lb
54/16=3.375lb
find per lb
4.89/3.375=$1.4488888 per lb
B.
2 and 3/4=2.75, 3.91/2.75=$1.42181 per lb
C. 910/453.59=2.00621lb
3.10/2.00621=$1.545 per lb
compare
A: $1.4488888 per lb
B: $1.42181 per lb
C: $1.545 per lb
B is cheapest, followed by A then C
B is best buy
