sale price=.7*19.49
1.0 - -0.3 = 0.7
To find the sale price of the shirt without using subtraction, you can use the concept of finding a percentage of a number. Here's how you can write an expression to find the sale price:
Step 1: Convert the percentage discount to a decimal. In this case, the discount is 30%, so you can write it as 0.30.
Step 2: Multiply the original price by the discount. The expression will be (1 - 0.30) * $19.49.
Now let's calculate the sale price of the shirt:
(1 - 0.30) * $19.49
= (0.70) * $19.49
= $13.64
Therefore, the sale price of the shirt is $13.64.
