9.84 = meal + (0.08)meal + (0.15)meal.

the answer is $8.00 but i do not see how it could be that.

$9.84=mealx + (.08)mealx + (.15)mealx
$9.84=mealx + .23mealx

I get stuck here.

\(\displaystyle \L
\begin{array}{l}
1m + .23m = 1.23m \\
\frac{{9.84}}{{1.23}} = ? \\
\end{array}\)

WHY do you not see "how it could be that" :?:

8 * .08 = .64
8 * .15 = 1.20
.64 + 1.20 = 1.84 :idea:
