Cost of fuel = 30% of $400 000 = 30/100 x 400000 = $120 000

Fuel amount = $120 000/$1.5 = 80 000 liters
new cost of fuel = 80000 x $1.6 = $144 000

increase in cost = 144000 - 120000 = $24000

So the increase in petrol price increases the operating cost by $24000

First we should change these mixed numbers into improper fractions:

12 \frac{4}{9}= \frac{112}{9}

1 \frac{7}{9}= \frac{16}{9}

We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:

\frac{112}{9} / \frac{16}{9}=\frac{112}{9} * \frac{9}{16} = \frac{1,008}{144}=7

So now we know that Otto used 7 crates.
