Two trains leave towns 1250 km apart at the same time and travel toward each other. one train travels 10 km/hr slower than the o

Oksana_A [137]

Here are the rates of the trains:
(n represents train A's speed)
A: n
B: n + 10
We know it is 5 hours, and total distance, so:
5(n) + 5(n + 10) = 1250
5n + 5n + 50 = 1250
10n = 1200
Divide:
n = 120
One train goes 120, the other goes 130

A markup of 33% based on cost is desired for a load of 800 bushels of peanuts. They were purchased at $5.85 per bushel. What sho

Alenkasestr [34]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of bushels of peanuts = 800

Price of each bushels of peanuts = $5.85

And there is mark up rate = 33%

So, Total price would be

$1.33\times 800\times 5.85\\\\=\$6224.4$

If there is spoilage rate = 21%

So, the remaining rate would be 1-0.21=0.79

so, Number of remaining bushels of peanuts would be

$0.79\times 800\\\\=632$

So, Selling price per bushel would be

$\dfrac{622.4}{632}\\\\=\$9.85$

Hence, Option 'c' is correct.
