An item is regularly priced at $77. It is now priced at a discount of 30% off the regular price.

$53.90

Step-by-step explanation:

30% of $77 = $77 * 30/100 = $77 * 0.3 = $23.10 (discount)

Regular price is $77, discount is $23.10, so the item is now

$77 - $23.10 = $53.90

Shorter way of solving this could be as follows:

The regular price is 100% of the price. If the item is on 30% discount, so it means now it worths 70% (which is 100% -  30%) of the regular price:

$77 * 70/100 = $77 * 0.7 = $53.90

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
