$18.99 per 340.23 grams ;
and given:
1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).
______________________________________________
Given: $18.99 per 340.23 grams ;
Convert: "340.23 grams" to "ounces (oz)".
Given: "1 gram ≈ 0.03527 oz" ;
340.23 grams = (340.23 * 0.03527) oz. = 11.9999121 (about "12 oz.").
So, $19 / 12 oz. = ? dollars per UNIT OZ. ; =
(19/12) dollars per oz. = (19÷12) dollars per oz. = $ 1.58333 ; which corresponds to: Answer choice: [C]: $1.58 .

P=2(l+w) = 9696
-> l+w= 9696/2= 4848
l=6+2w
6+2w+w=4848
6+3w=4848
3w=4842
w=1614
l=6+2w = 6+2x1614= 3234
