A travel agent offers a vacation plan which costs x dollars for the first day, and x/6 for each additional day. How much does a vacation of y days cost, where y > 1.

yz/6 yz/3 (yz+6z)/6 (yz+5z)/6 (y2z+5yz+z2)/3

According to me it has to be C, but OA is different. Its from Kaplan 800

Lets say 2 days travelled => y = 2 and lets say first day charged $6 and the 2nd day the amount would be x/6 =>$6/6 = $1 So, for the 2(Y) days, he/she suppoed to pay $6 ( 1st Day charge)+ $1 (2nd charge) = 7

now substitute the values for y = 2 and x= 6 ( In this case, x value = z value )
