Question
A school has $15,000 to spend on computer monitors. The school plans to purchase 200 monitors for $89 each.
A teacher completes the calculations below and concludes that the school has enough money to buy the monitors.
200×89===(200×8)+(200×9)1,600+1,8003,400
The teacher's calculations are incorrect. Using the correct calculations:
200 x 89 = 17,800
So the total cost of purchasing 200 monitors at $89 each is $17,800.
Since the school only has $15,000 to spend, they do not have enough money to buy the monitors.
