If 30 lb of rice and 20 lb of potatoes cost $18.20, and 20 lb of rice and 12 lb of potatoes cost $11.52, how much will 10 lb of rice and 50 lb of potatoes cost? let x be the cost of 1 lb of rice and y be the cost of 1 lb of potatoes. set up two linear equations from the given information using x and y as the variables.

⇒let the cost of 1 Ib of rice be "x" and that of 1 ib of potatoes be "y" 
               
         30x + 20y = 18.20equation ( i )
          20x + 12y =11.52equation ( ii )

⇒30x + 20y = 18.20×2
⇒20x + 12y = 11.52×3

          60x + 40y = 36.40
          60x + 36y = 34.56
                  ↓
            4y = 1.84
              y = 0.46

value of x.
30x = 18.20 - 20(0.46)
 30x = 9
    x = 0.3

 cost of 10 ib of rice and 50 ib of potatoes?
      10x + 50y = ?
      10(0.3) + 50(0.46) = 26

Answer = 26 Dollars

Idon’t know what the answer is i wish i could
