Solution
The correct option is C Six Jim bought purple tomato for $8 each. Aubrey bought organic cabbage for $12 each. Total money paid =$104 Total number of vegetables =10 Let number of tomato bought be x So, number of cabbage bought will be =(10−x) As per problem, we have 8x+12(10−x)=104 ⇒8x+120−12x=104 ⇒4x=16 ⇒x=4 Number of cabbages bought is (10−4)=6.
