100grams x 4 = 400grams
100 grams of cereal= 49p
49p x 4 = 196 p
If 100grams of cereal equals to 49p then 400 grams is 196p ( 49p x 4)
If 100 grams of pasta = 14 p
then 500 grams of pasta = 700p
But we want to find 250 grams of pasta ……500grams /2 = 250grams so 700p /2= 350p which is the cost of 250 grams of pasta
The total cost = cost of the 400 grams of cereal + cost of the 250 grams of pasta
196p + 350p = 546p is the total BUT we want the answer in pounds so we divide 546p by 100 = £5.46
The total cost is £5.46
