A chair costs 1/7 of the cost of a table. If a table costs $140, how much will it cost to buy a table and 4 chairs?
One chair costs $140 x 1/7 = $
<gadget id="calculator">140*1/7</gadget>
<output>20</output>
20.
Four chairs cost $20 x 4 = $
<gadget id="calculator">20*4</gadget>
<output>80</output>
80.
So a table and 4 chairs cost $140 + $80 = $
<gadget id="calculator">140+80</gadget>
<output>220</output>
220.
