Question

Justin's hair is 314314 inches long. How long will it be in 22 months if it grows 1212 inch each month? which method will not give the correct number of inches?.

Answer 1

147466

Explanation:

y = total length of hair

x = number of months

y = 1212x + 314315 Substitute in 22 for x

y = 1212(11) + 314314

y = 147466

I am not sure which method would not work.
