A school has $15,000 to spend on computer monitors. The school plans to purchase 200 monitors tor $89 each
A teacher completes the calculations below and concludes that the school has enough money to buy the monitors.
200 x 89 = (200 x 8) + (200 x 9)
= 1,600 + 1,800
= 3,400
Which explains whether or not the teacher's conclusion is correct?
A
00:00
The teacher did not use the Distributive Property correctly.
200 x 89 = (200 + 8) x (200 + 9) = 208 209 = 43,472
The total cost of the monitors is $43,472, which is more than $15,000.
So, the teacher's conclusion is not correct.
B.
00:00
The teacher did not use the Distributive Property correctly
200 x 89 = (200 x 89) + (1 x 89) = 17,800 + 89 = 17,889
The total cost of the monitors is $17,889, which is more than $15,000.
So, the teacher's conclusion is not correct.
00:00
The teacher did not use the Distributive Property correctly.
200 x 89 = (200 x 80) + (200 x 9) = 16,000 + 1,800 = 17,800
The total cost of the monitors is $17,800, which is more than $15,000.
So, the teacher's conclusion is not correct.
D
00:00
The teacher used the Distributive Property correctly to show that the total
cost of the computers is $3,400, which is less than $15,000.
So, the teacher's conclusion is correct.
