1)
$1 x 35%
= $1 x 35/100
= $1 x 7/20
= $7/20
= $0.35

2)
$5 x 35%
= $5 x 35/100
= $5 x 7/20
= $35/20
= $7/4
= $1.5

3)
$10 x 35%
= $10 x 35/100
= $10 x 7/20
= $70/20
= $3.5

4)
$29.99 x 35%
= $29.99 x 35/100
= $29.99 x 7/20
= $209.93/20
= $10.4965
≈ $10.5

5)
$29.99 x 30%
= $29.99 x 30/100
= $29.99 x 3/10
= $89.97/10
= $8.997
≈ $9
