The price of a swimming pool

Goryan [66]

Answer:

$Sales\:\:Price=List\:\:Price-Discount$
Sales price= $ $1167.25$ List price=L Discount $=19.5\%\:of\:L=0.195L$
$1167.25=L-0.195L$

Step-by-step explanation:

The percentage discount is $19.5\%$

The discount is always given on the list price.

$Sales\:\:Price=List\:\:Price-Discount$

Let the list price be L, then

List price=L

Sales price= $ $1167.25$

Discount $=19.5\%\:of\:L=0.195L$

We substitute into the equation to get:

$1167.25=L-0.195L$

$1167.25=0.805L$

Divide both sides by 0.805

$\frac{1167.25}{0.805}=L$

$1450=L$

The list price of the swimming pool is $1450
