In the given question the most important part is convert ounce to pound and then the problem becomes easy. We already know
1 ounce = 0.0625 pounds
Then
24 ounce = 0.0625 * 24 pounds
= 1.5 pounds
Now let us focus on the problem in hand and the information's that are already given in the question.
The cost per pound of the sandwich sold by Deli = 6.40
Then
The cost of 1.5 pound of sandwich sold by Deli = 6.40 * 1.5
= 9.60
So the cost of 24 ounces of spread is 9.60.
I think the answer may be C
Set up a system of equations.
6s+b=139.5
b=3s
Substitite for b
6s+3s=139.5
9s=139.5
s=15.5
Now multiply by 3 to get the blazer price
15.5*3= 46.5
Final answer: $46.50
