Henry purchased compact disks for $112. The compact discs cost $16 each. Which of the following equations could you use to find how many compact disks, x, Henry purchased? $16 = $112x $112 = $16x $112 = x/16 $112 = x - $16
however many you buy, the total equals 112. so the 112 is what the cost of the cd's is equal to. 112= Now we need to decide the other side. If each cd costs 16, the thing in question is how many you buy. x will be how many you buy, it's the unknown, the only thing you do not know for sure. So if each cd costs 16, and you buy x amount of cd's at 16 apiece, what is the expression for that?
idk
an unknown number of cd's at 16 each is 16x. So what is the whole equation?
112=16x. That is the equation that tells you that a certain number of cd's at 16 dollars apiece costs you 112.
