(A) Explanation Given that, the drug which costs $85 and $175 is sold for $112 and $238, respectively. Let R represents the retail price and C represents the cost price . The given information can be expressed in terms of ordered pair as ( 85 , 112 ) and ( 175 , 238 ) . It is given that cost price and retail price are linearly related and hence, the line representing will definitely passes through the points ( 85 , 112 ) and ( 175 , 238 ) . Thus, the linear equation is obtained as, ( R − 112 ) = ( 238 − 112 ) ( 175 − 85 ) ( C − 85 ) (B) To determine The cost of the drug whose retail price is $185.
