Question

The number of customers for a new online business can be modeled by y = 8x2 + 100x + 250, where x represents the number of months since the business started. Which is the best prediction for the number of customers in month 20?

Answer 1

The best prediction for the number of customers is 5450.

To find this value, you just need to plug in 20 for x into the expression. Then, evaluate it using the order of operations.

8(20)^2 + 100(20) + 250
8(400) + 100(20) + 250
3200 + 2000 + 250
5450
