Question

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?

Answer 1

Answer:

Step-by-step explanation:

Total cost of compact disk = 112

Cost of each compact disk = 16

Number of compact disk = x

So equation will be:

16x = 112

x = 7

Answer 2

CORRECT QUESTION

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?

(a)$112=x-$16

(b) $112=$16x

(c) $16=$112x

(d) $112=(x)/(16)

ANSWER

The equation used is 16x = $112

GIVEN

Henry purchased compact disks for $112. The compact discs cost $16 each.

TO FIND

Which of the following equations could. you use to find how many compact disks, x, Henry purchased.

SOLUTION

We can simply solve the above problem as follows,

It is given,

Let the number of disks purchased = x

Cost of 1 disk = $16

Cost of x disks = 16 × x = $16x (i)

Total Cost of disks purchased = $112 (ii)

Equating (i) and (ii)

The equation thus formed,

16x = $112

We can find out the value of x by dividing 16 to whole equation;

16x/16 = 112/16

x = 7

Hence, The equation used is 16x = $112
