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
The weight of one chair is [tex]\fbox{\bf9.73\,{\text{lb}}}[/tex].
Further explanation:
The weight of a table and 8 chairs together is [tex]235.68\,{\text{lb}}[/tex].
The weight of the table is 157.84 lb.
Therefore the weight of 8 chairs is calculated as follows:
[tex]235.68-157.84=77.84[/tex]
The weight of 8 chairs is obtained as 77.84 lb.
Consider the cost of 1 chair as [tex]x[/tex].
Then the cost of 8 chairs can be written as [tex]8x[/tex].
Therefore the equation can be written as follows:
[tex]\begin{aligned}8x&=77.84\hfill\\x&=\frac{{77.84}}{8}\hfill\\x&=9.73\hfill\\\end{aligned}[/tex]
Here, [tex]x[/tex] represents the weight of 1 chair.
Thus, the weight of 1 chair is obtained as [tex]\fbox{\bf9.73\,{\text{lb}}}[/tex].
