To determine what [tex]\(15 \%\)[/tex] of 70 is, we follow these steps:
1. Understand that [tex]\(15\%\)[/tex] means [tex]\( \frac{15}{100} \)[/tex], which is a way to convert the percentage to a decimal for easier multiplication.
2. Multiply [tex]\( \frac{15}{100} \)[/tex] by 70 to find [tex]\(15 \%\)[/tex] of 70.
So we rewrite the expression as:
[tex]\[ 15 \% \text{ of } 70 = \frac{15}{100} \times 70 \][/tex]
3. Now calculate the multiplication:
[tex]\[ \frac{15}{100} \times 70 = 0.15 \times 70 \][/tex]
4. Perform the multiplication:
[tex]\[ 0.15 \times 70 = 10.5 \][/tex]
Thus, [tex]\( 15\% \)[/tex] of 70 is [tex]\(\boxed{10.5} \)[/tex], which matches option B: [tex]\( 10.50 \)[/tex].
