d) 45 - 10y


  1. c)

  2. d)

  3. b)

  4. a)


Solution

The correct option is A

c)


 Cost of y food packets=cost of 1 food packet × number of food packets 

=> Cost of y food packets=45×y

=> Cost of y food packets=45y      

Total cost = cost for y food packets + fixed charge    

=>  Total cost = 45y + 10
