Alex chose a pair of jeans that sells for $19.50, but today all jeans are on sale for 10% off. How much will Alex save. Explain your answer.

$1.95

Step-by-step explanation:

Old Cost price = $19.50

Discount Percent = 10%

Discount = 10% × $19.50

= 10/100 × $19.50

= 0.1 × $19.50

= $1.95

Therefore, Alex will save $1.95
