Shaan is moving to an apartment with his partner. He wants
to spend $ 850 on a dining table with four chairs. If the cost of four chairs
is “x” and the cost of a table is $100 more than the cost of a chair, then what
will be the cost of chairs and table? (excluding
taxes).
Let
Cost of
four chairs = x
Cost of
a chair = x/4
Cost of
a table = (100 + x/4)
Total
amount = $850
So,
x + (100
+ x/4) = 850
Try x = 100,
100 +
125 = 225 ≠ 850
We need approximately four times the answer to get 850
Now try x = 400
400 +
200 = 600 ≠ 850
Try x = 600
600 +
250 = 850
So, the cost of four chairs is $ 600 and the cost of
one chair is $150
The cost
of a table is $250.
Hmmm -- Amrit, I am not sure if you have fully grasped the idea of ancient Egyptian false position, but good try! We will work together on this in class today.
ReplyDeleteActually, this is fine -- it's the constant amount (100) that makes it harder to estimate proportionally!
