11 boys and 8 girls because you divide it in half the add 2 and subtract 1. That isn't the wy you are supposed to do it but it works and makes since in my head.
In 1 and 2, you are asked to find "a" and "b" in the pattern
g(x) = a•bˣ
1: selection 2
2: selection 4
3. You want the result of evaluating 4000*(1.06)⁵ ≈ 5352.90, selection 2.
$540
Explanation:
7.5% of 1800 is 135
135 • 4 = 540
6(3+4) is the right answer because when you distribute you get 18+24.
Hope this helps!!
