well, first off let's find what 15% of the meal cost is anyway, so, what's 15% of 46.40?
if we take 46.40 as the 100%, well, let's check what is the 15% of that.
[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 46.40&100\\ x&15 \end{array}\implies \cfrac{46.40}{x}=\cfrac{100}{15}\implies \cfrac{46.40\cdot 15}{100}=x[/tex]
so, the total cost is then, 46.40 + x.
