$17.5$ $17.5$

Explanation:

Move the decimal place of 3.5 two times to the left because it's a percent.

$3.5 % = .035$ $3.5%=.035$

Now multiply $.035$ $.035$ to 500.

$.035 \cdot 500 = 17.5$ $.035*500=17.5$

17.5

Explanation:

The symbol % is like a unit of measurement that is worth $\frac{1}{100}$ $1/100$

So $3.5 % \to 3.5 \times \frac{1}{100} = \frac{3.5}{100}$ $3.5%" "->" "3.5xx1/100 = 3.5/100$

The use of the word 'of' is interpreted as multiply

Like in 2 of apples $= 2 \times$ $=2xx$ apples = apples + apples

So 3.5% of 5000 is the same as:

$\frac{3.5}{100} \times 500$ $3.5/100xx500$

However, 500 is the same as $5 \times 100$ $5xx100$ so we can write this as:

$3.5 \times \frac{1}{100} \times 5 \times 100$ $3.5xx1/100xx5xx100$

$3.5 \times 5 \times \frac{1}{100} \times 100$ $3.5xx5xx1/100xx100$

$3.5 \times 5 \times \frac{100}{100}$ $3.5xx5xx100/100$

$3.5 \times 5 \times 1$ $3.5xx5xx1$

$3.5 \times 5$ $3.5xx5$

$3.5 \times \frac{10}{2} = \frac{35}{2} = 17.5$ $3.5xx10/2" "=" "35/2=17.5$
