Q.10 The cost of a magazine is $x and the cost of a newspaper is $(x -3). The total cost of 6 magazines and 9 newspapers is $51. Write down and solve an equation in x to find the cost of a magazine,

Answer and Step-by-step explanation:

The cost of all the 6 magazines are: 6x

The cost of all the 9 newspapers are 9(x-3)

So, the total cost is the sum of all the items:

6x + 9(x-3) = 51

6x + 9x - 27 = 51

15x = 78

x = 5.2

Since the cost of one magazine is $x, the cost will be $5.20.
