Question

a table and 8 chairs weigh 235.68lb together if the table weighs 157.84 lb, what is the weight of one chair in pounds

Answer 1

The weight of one chair is $\fbox{\bf9.73\,{\text{lb}}}$.

Further explanation:

The weight of a table and 8 chairs together is $235.68\,{\text{lb}}$.

The weight of the table is 157.84 lb.

Therefore the weight of 8 chairs is calculated as follows:

$235.68-157.84=77.84$

The weight of 8 chairs is obtained as 77.84 lb.

Consider the cost of 1 chair as $x$.

Then the cost of 8 chairs can be written as $8x$.

Therefore the equation can be written as follows:

$\begin{aligned}8x&=77.84\hfill\\x&=\frac{{77.84}}{8}\hfill\\x&=9.73\hfill\\\end{aligned}$

Here, $x$ represents the weight of 1 chair.

Thus, the weight of 1 chair is obtained as $\fbox{\bf9.73\,{\text{lb}}}$.

Answer 2

Answer:

9.73 lb

Step-by-step explanation:

The total together is 235.68 lb.  Taking away the weight of the table, 157.84, we are left with

235.68-157.84 = 77.84 for the weight of all of the chairs.  Dividing this by 8 gives us the weight of one chair:

77.84/8 = 9.73
