Solution:
To find the cost of producing 100 tools using the given equation (Cost = 110Y - 500), we need to substitute Y with 100, where Y represents the quantity of tools produced.So, we replace Y with 100:Cost = 110 * 100 - 500Therefore, the expression that represents the cost of 100 tools is:110 * 100 - 500This matches option A, so the correct answer is:A) 110 * 100 - 500
