Respuesta :
we have given for 12 ounces is $40.80.
we need to find the rate for unit ounce.
we know that [tex] 12 [/tex][tex] ounces =$40.80 [/tex]
[tex] 1 [/tex][tex] ounce=\frac{40.80}{12} =3.4 [/tex].
so one ounce cost about $3.4.
40.80 divided by 12 would be 3.4 therefore, the unit rate is $3.40 per ounce.
