Answer:
h = 9 ft
Step-by-step explanation:
Assume the diagram is like the one below.
∆ABD is a right triangle.
We can use Pythagoras' Theorem to find the height h.

100 = number of sets of clubs manufactured per month
S = sell-price for a set of clubs
Expenses per month = 23,250 + 145(100) = 37,750
Revenue per month = 100 S
Break-even when Expenses = Revenue
<u>100 S = 37,750</u>
One question: How did you solve it without an equation ?
X // Y, Y // Z,
By inference X // Z
The third option.
