Here is what you need to find:
[tex] 70\%\ of\ 8,000 [/tex]
Change 70% to a decimal and multiply by 8,000.
To change a percent to a decimal, move the decimal point 2 places to the right and remove the percent sign.
[tex] 70 \% \rightarrow 0.7 [/tex]
Now multiply by 8,000.
[tex] 0.7 \times 8,000 = 5,600 [/tex]
70% of 8,000 is 5,600
