Explanation

consider the first row

sum of 1st row is 30 and there is 3 pair of shoe so we can divided by 3 then we can find the price of 1 product

price of first product 10

consider the second row

there are 3 product and the sum is 20 and we also know the value of shoe is 10,  so 2 dolls+10 = 20

so value of doll is 5

consider the third row

the sum of third row is 13. and we know the value of doll is 5

so value of pair of ice cream value is (13-5)/2 value is 4

consider the fourth row

there is 1 shoe 1 doll and 1 ice cream = 5 + 5 x 4

                                                             = 5 + 20

                                                             = 25
