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.
To find out how much each of the equal payments is, we first need to calculate the total cost of the books.
The total cost of the four rare books is $130 + $120 + $80 + $75 = $405.
According to the given information, Steven paid 1/3 of the total cost immediately, which is (1/3) * $405 = $135.
Now we need to find out how much he paid in three equal payments. To do this, we subtract the amount he paid immediately from the total cost of the books: $405 - $135 = $270.
Since he wants to pay this amount in three equal payments, we divide $270 by 3: $270 / 3 = $90.
Therefore, each of the equal payments Steven needs to make is $90.
