s=sweaters, p=pants

a)  35s + 20p =$150

 

b)  35*3 + 20p =$150

       105  + 20p =$150 subtract 105 from both sides

        20p =150 - 105

        20p =45                 divide both sides by 20

         p =45/20

         p=2.25 =2 pants that she can buy.

 

c)   35s + 0p = $150

       35s = $150       divide both sides by 35

        s =150/35

        s=4 2/7 = 4 sweaters that she can buy.
