D. ___$4.57___

Answer 1

Hi Jade,

 

Cost of 3 pounds of onions = $2.67

Cost of 1 pound of onions =$ 2.67/3

                                      =$0.89

 

In the options they are calculating for 4 pounds and 5 pounds

 

Cost of 4 pounds of onions = 4×.89=$3.56

Cost of 5 pounds of onions = 5×.89=$4.45

 

so this shows that the answer C is right   $4.45/5pounds
