A farmer spent $35 on feed for chickens and goats. He spent

You can write one equation right away I just broke down the solution into several steps to make it easier. If interested here it is: 0.4*35/0.8+0.6*35=38.5. Notice that you should divide 0.4*35 by 0.8 to get original price and not multiply.

As always my question. This questin is quite easy but a lot of work to write and to calculate. I would suggest it is a question between 600 - 700 ? Without a calculator it is very time consuming.

guys here is an easier way:
Let the farmer had 100 to spend.
He spent 40 on chickens and 60 on goats.
now actual price of chicken feed without discount
x-20%x=40
0.8x=40 or x=50
So without discount he would have spent 50+60=110
Now 110 for 100
For 35 it is 110/100*35=38.5

He spent 40% of 35 on chicken feed, i.e 35*40/100= 14

This $14 was 80% (He got 20% discount), So the actual price without discount was= 14*100/80= 17.5

Amount spent on goat feed= 35-14= 21

Total price without discount= 21+17.5= 38.5

B is the answer

We know 60% of $35 was spent on goats, leaving us with $14 spent on chickens.

$14 spent was with discount --> $14 = x-0.20x --> 14 = 0.80x --> x = $17.5 (original price)

$17.5+$21 = $38.5

The farmer spent 35 x 0.4 = 14 dollars on feed for chickens and thus 21 dollars on goat feed.

If we let p = the regular price of the chicken feed we can create the equation:

0.8p = 14

p = 14/0.8 = 17.5

Thus, if the farmer paid regular price for both feeds, he would have spent 17.5 + 21 = $38.50.

Answer: B

Hi All,

This question is essentially about arithmetic and taking the proper notes. You can go about the math steps in a couple of different ways though - depending on how you 'see' this information.

From the prompt, we know that the farmer spent $35 on feed.... 40% of his money on chicken feed.... and the rest on goat feed. This means that for every dollar he spent, $0.40 was spent on chicken feed and $0.60 was spent on goat feed. With a total of $35 spent, we can easily break down the two totals....

(.4)($35) = $14.00 on chicken feed
The rest = $35 - $14 = $21 on goat feed

We were also told that the chicken feed was purchased at a 20% discount, which means that the farmer paid 80% of the regular price for that feed.

$14.00 = (.8)(Regular Price)
$14/.8 = (Regular Price)
$140/8 = (Regular Price)
$17.50 = (Regular Price)

We're asked what the price would have been if the farmer had bought both feeds at full price.... $21 + $17.50 = $38.50

Final Answer:

We're told a farmer spent $35 on feed for chickens and goats

He spent 40% of $35 for chicken feed:

40% of 35 = $14
60% of 35 = $21

He bought the chicken feed for 20% discount; therefore if he purchased the chicken feed at full price he would have spent:

\($14 = 0.8x\)

\(\frac{14}{0.8} = x\)

\(17.5 = x\)

\($17.50 + 21 = $38.50\)

Answer is B.
