Sahara already knows 4 dance moves. She decides to take dance lessons to learn more new moves. The instructor tells her that she can learn two new moves each week.
Which functional equation can be used to find the number of dance moves (d) that Sahara knows after w weeks of lessons?
Choose:
d = 2w + 4
d = 4w + 2
d = 2w + 10
d = 2w - 4
d=2w+4
