Question

A spark plug listed at $1.89, marked down 29%

Answer 1

$1.34

Explanation:

The price of a spark plug = $1.89

It was marked down = 29%

29 percent of 1.89 = 29% × 1.89

=
`(29)/(100)* 1.89`

= 0.29 × 1.89

= 0.5481 ≈ $0.55

The new price of spark plug = 1.89 - 0.55

= $1.34

The new price after 29% marked down is $1.34.

Answer 2

29% = 0.29

Multiply 1.89 with 0.29

1.89 x 0.29 = 0.5481

Note that it is a markdown, so subtract 0.55 (rounded) with 1.89

1.89 - 0.55 = 1.34

The spark plug now costs ~ $1.34

hope this helps
