Answer:
d. 9
Explanation:
The equation: y = 0.22x^2 - 1.76x + 4.75
x: Time in months
y: Number of laptops sold
Since we need to predict the number of laptops that will be sold during month 10, we can replace the x with 10.
The new equation will be: y = 22 - 17.6 + 4.75
Then y will be 9.15
Since there cannot be 0.15 of a laptop, we round the number 9.15 to a whole number, which is 9.
D) 9 is our final answer to this question.
