Question

KOFI electronics bought a shipment of TVs at a net price of $477.36 each, after discounts of 15%, 10%, and 4%. What is the list price?

Answer 1

let $x$ represent the price of each items and A, B, C represent each item

.: $price -discount =netprice$

i) item A:

$x-15x$% = 477.36

$x-\frac{15x}{100}=477.36$

$\frac{85x}{100}=477.36$

$85x$ = 100 × 477.36

$x$ = $\frac{100 × 477.36}{85}$

$x=561.6$

ii) item B:

$x-10x$% = 477.36

$x-\frac{10x}{100}=477.36$

$90x=$ 100 × 477.36

$x=\frac{100 × 477.36}{90}$

$x=530.4$

iii) item C:

$x-4x$% = 477.36

$x-\frac{4x}{100}=477.36$

$96x=100×477.36$

$x=\frac{100 × 477.36}{96}$

$x=497.25$

Therefore, the list price of each of the item is $561.6, $530.4 and $497.25
