How many pounds of candy would be for $1? Explain your answer.

Answer 1

Explanation:

No you cannot even buy a candy for 1

Answer 2

Answer: a) $6.20 per pound b) 5/31 pound per $1

Explanation:

`(\$18.60)/(3\ lbs)/ (3)/(3)=(\$6.20)/(lb)\quad \rightarrow \quad \large\boxed{\$6.20\ per\ lb}`

`( 1\ lb)/(\$6.20)/ (6.20)/(6.20)=((1)/(6.20)\ lb)/(\$1.00)\quad =((10)/(62)\ lb)/(\$ 1.00)\quad =((5)/(31)\ lb)/(\$1.00)\quad \rightarrow \quad \large\boxed{(5)/(31)\ lb\ per\ \$1}`
