Final answer:
To relate the total cost, y, to the number of pounds of turkey, x, we can use the equation y = 6.8x.
Step-by-step explanation:
To write the equation relating the total cost, y, to the number of pounds of turkey, x, we can use a similar approach as the examples given. Let's define y as the total cost and x as the number of pounds of turkey.
Based on the given information, PJ bought 1.25 pounds of sliced turkey for $8.50. We can write the equation y = kx, where y represents the total cost and x represents the number of pounds of turkey.
To find the value of k, we divide the total cost by the number of pounds of turkey: k = 8.50 / 1.25 = 6.8.
Therefore, the equation relating the total cost, y, to the number of pounds of turkey, x, is y = 6.8x.
