Customers can pick their own pumpkins at the great pumpkin patch. they pay 4$ to enter the patch and 3$ per pound for the pumpkins they pick. write an equation to model the total cost ,y ,for x pounds of pumpkins

Given, Customers pay $4 to enter the pumpkin patch.

And also given, customers pay $3 per pound for the pumpkins.

Given, $y be the total cost and there are x pounds of pumpkins.

The cost for pumpkin per pound = $3.

Therefore, the cost for x pound pumpkins = $(3x)

As the total cost includes the payment for entering the patch also,

So the total cost y = 3x + 4

We have got the required equation.

The equation to model the total cost is y = 3x+4.

yes. we do proportions in probabilities.
