Question 254132
Given, Cones cost $1.10 and sundaes cost $2.35
Let the number of cones bought = x
Let the number of sundaes bought = y
Given,    x+y = 172         ...(1)
Total cost 1.10x + 2.35y = 294.20
          Multiplying by 100, we get
           110x+235y = 29420 ...(2) 
(1)*110 => 110x+110y = 18920 ...(3)
(2)-(3) =>      125y = 10500
                   y = 10500/125
                   y = 84
Substituting in (1), we get 
              x+84 = 172
                 x = 172-84
                 x = 88
Therefore, the number of cones bought = 88
and  the number of sundaes bought = 84
