steven bought four rare books that cost $130, $120, $80 and $75 respectivily. if he paid 1/3 of the total cost immediatly and the remainder in three equal payments, how much was each of the equal payments? please show work.

130 + 120 + 80 + 75 = ?
Multiply the above sum by 2/3.
Divide the above product by 3. 
i got 67 but that cant be the answer . . . . the choices are $45 $55 $70 $90 $135

so what do i do now?

130 + 120 + 80 + 75 = 405
405 * 2/3 = 810/3 = 270
270 / 3 = ? 
oh it equals 90 thank you so much for the help im sorry i added it wrong the first time but thanks so much :)

You're very welcome.
