Answer:
a_n = a_(n-1) + 3 where a_1 = 2
a_7 = 20
Step-by-step explanation:
here a_n is denoting the number of hexagons that show up in the diagram.
starting with a_1 = 2
a_2 = a_1 + 3 = 2 + 3 = 5
a_3 = a_2 + 3 = 5 + 3 = 8
a_4 = a_3 + 3 = 8 + 3 = 11
a_5 = a_4 + 3 = 11 + 3 = 14
a_6 = a_5 + 3 = 14 + 3 = 17
a_7 = a_6 + 3 = 17 + 3 = 20
the function is decreasing and the y intercept is (0,1)

Answer:
- 8 white shirts
- 22 colored shirts
Step-by-step explanation:
Let c represent the number of colored shirts sold. Then c-14 is the number of white shirts sold. The total revenue is ...
10.50c +9.95(c -14) = 310.60
20.45c -139.30 = 310.60 . . . . . . simplify
20.45c = 449.90 . . . . . . . . . . add 139.30
c = 22 . . . . . . . . . . . . . . . . . divide by 20.45
c-14 = 8
22 colored shirts and 8 white shirts were sold.
