Let's break down the situation to check whether the school has enough budget for the purchase of 200 computer monitors at $89 each.
-
Calculate the total cost of the monitors: \[ \text{Total cost} = \text{Number of monitors} \times \text{Cost per monitor} \] \[ \text{Total cost} = 200 \times 89 \] \[ \text{Total cost} = 17800 \]
-
Compare the total cost with the budget: The school has a budget of $15,000.
-
Determine if the budget is sufficient:
- Total cost of monitors: $17,800
- Budget available: $15,000
Since the total cost of $17,800 exceeds the budget of $15,000, the school does not have enough money to purchase the 200 monitors at that price. The teacher's conclusion that the school has enough is incorrect based on these calculations.
