At a mall's food court, Crystal has $\$7.50$ to buy a meal (one entree, one drink and one dessert). The table below lists Crystal's choices and their prices including sales tax. How many distinct possible meals can she afford to buy? \[\begin{array}{|c|c|c|} \hline \text{Entrees} & \text{Drinks} & \text{Desserts} \\ \hline \text{Pizza } \$3.50 & \text{Lemonade } \$1.50 & \text{Frozen Yogurt } \$3.00 \\ \hline \text{Corn Dog } \$2.50 & \text{Soda } \$1.25 & \text{Cookies } \$2.00 \\ \hline \text{Fish~\& Chips } \$3.50 & & \\ \hline \text{Fried Rice } \$4.75 & & \\ \hline \end{array}\]
+208 She has four options for Entrees.
She has 2 options for drinks
She has 2 options for desserts.
4*2*2=16
But some possibilities go over her budget. These are the possibilities:
P-L-FY=8
P-S-FY=7.75
F&C-L-FY=8
F&C-S-FY=7.75
FR-S-C=8
FR-S-FY=9
FR-L-C=8.25
FR-L-FY=9.25
these are 8 possibilities.
So, she has 16-8=8 distinct possible meals.
