$69.60

20% is $\frac{20}{100}$ $20/100$

"of means multiply" so 20% of $58.00 means

$\frac{20}{100} \cdot $ 58.00 = $ 11.60$ $20/100*$58.00 = $11.60$ (this is the tip)

So altogether she spent $58.00 + $11.60 = $69.60

$$ 69.60$ $$69.60$

$20 % \times $ 58.00 = $ 11.6$ $20% xx $58.00 = $11.6$

$$ 58.00 + $ 11.6 = $ 69.60$ $$58.00 + $11.6 = $69.60$

It is easier to multiply $100 % + 20 %$ $100%+20%$ i.e. $1.2$ $1.2$ by the cost of her meal :
$1.2 \times $ 58.00 = $ 69.60$ $1.2 xx $58.00 = $69.60$
