The cost per pound of the strawberries is given by the expression y−3.75/x.
In this scenario, the total cost (y) includes the cost of strawberries and a fixed cost for the pie crust, which is $3.75. The equation y= y−3.75/x expresses the relationship between the total cost, the weight of strawberries (x), and the cost per pound of strawberries.
To isolate the cost per pound of strawberries, we subtract the fixed cost from the total cost to get the cost of strawberries alone (y−3.75). Dividing this value by the weight of strawberries (x) provides the cost per pound.
Therefore, the expression y−3.75/x gives us the cost per pound of strawberries in David's strawberry milkshake endeavor. It's a useful formula for understanding the cost associated with each pound of strawberries in the context of preparing the milkshake, taking into account both variable and fixed costs.
