Step-by-step explanation:
The total cost of buying 4 drinks and 4 pretzels can be calculated by multiplying the price of each item by the number of items purchased and then summing up the costs.
Let's assume the prices of the drinks are $Pd1, $Pd2, $Pd3, and $Pd4 and the prices of the pretzels are $Pp1, $Pp2, $Pp3, and $Pp4. The total cost can be expressed as:
Total Cost = ($Pd1 + $Pd2 + $Pd3 + $Pd4) + ($Pp1 + $Pp2 + $Pp3 + $Pp4)
