Question

What does it mean to solve an equation? A business ordered 3 keyboards and a monitor from a computer company, HiTech, and sent in a payment of $675 with the order. The keyboards cost $25 each, but the cost of the monitor was missing. Using words, describe what equation the business could use to find the cost of the monitor.

Answer 1

Solving an equation involves finding the value of the variable that makes the equation true. In the given business scenario, the equation to determine the monitor's cost is M + 3($25) = $675. Subtracting $75 from both sides provides the cost for the monitor.

Step-by-step explanation:

To solve an equation means to find the value of the variable that makes the equation true. In the scenario where a business ordered 3 keyboards at $25 each and a monitor from HiTech and sent a payment of $675, we need to determine the cost of the monitor. Let's denote the cost of the monitor as M. We know the total cost of the keyboards is 3 multiplied by $25, which is $75. The equation the business would use to find the cost of the monitor can be formulated as:

M + 3($25) = $675

This simplifies to M + $75 = $675. To find the value of M, we then subtract $75 from both sides of the equation which gives us:

M = $675 - $75

After calculating, we will find out the cost of the monitor which the business needs to know.
