Question

At a supermarket, the price of a Thanksgiving turkey is determined by how many pounds the turkey weighs. The price of a 12.4 pound turkey is $15.50. Write an equation that can be used to determine the price, p, in dollars, of any turkey based on the number of pounds, t, the turkey weighs. Explain the process you used to determine the equation.

Answer 1

The expression is:
`p = 1.25*t`

Explanation:

Since the price is determined by the weight of the turkey, we need to find the value of one pound in order to create the expression, to do that we will apply the point given.

`\text{price per pound} = \frac{\text{price}}{\text{weight}}\\\text{price per pound} = (15.5)/(12.4) = 1.25`

Each pound costs $1.25, therefore the expression used to calculate the price of the turkey must be the weight of the turkey in pounds multiplied by the price of each pound.:

`p = 1.25*t`
