The second plan of company B charge Rs 40 per month, but calls cost 8 paise per minute. These two situations are shown below in the form of linar equations. The total cost of the two company's are given as : y =0.25 x + 20 and y = 0.8x + 40 Where, x is the minutes used any y is the total cost per month. If Rajesh decides to take first plan and calls for 90 minutes in a month, then how much amount he will have to pay ?
