Final answer:
After purchasing 4 salads and accounting for the delivery charge, Alex can spend the remaining $32 of his $70 budget on drinks. Each drink costs $4, so he can buy a maximum of 8 drinks.
Step-by-step explanation:
The problem involves determining the maximum number of drinks Alex can buy with his remaining budget after purchasing salads and accounting for a delivery charge. First, let's calculate the total cost of the salads and the delivery charge:
Cost of 4 salads = 4 × $8 = $32
Delivery charge = $6
Total cost for salads and delivery = $32 + $6 = $38
Alex has $70, so the remaining budget for drinks is:
Remaining budget = Total budget - Total cost for salads and delivery
Remaining budget = $70 - $38 = $32
Now, we divide the remaining budget by the cost of each drink to find the maximum number of drinks he can buy:
Cost per drink = $4
Maximum number of drinks = Remaining budget ÷ Cost per drink
Maximum number of drinks = $32 ÷ $4
Maximum number of drinks = 8
Hence, the correct answer is A. 8 drinks.
