<h3>Answer: B) 50%</h3>

Work Shown:

P = original price = 24

Q = discount price = 12

P-Q = amount saved = 24-12 = 12

Divide this amount over the original

(P-Q)/P = 12/24 = 0.50 = 50%

So you save half (save $12) and pay the other half (pay $12)

Let
x = the number of shorts bought
y = the number of t-shirts bought

A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10 (1)

Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2 (2)

Graph the equations y = -1.6x + 10 and x = 2.
The shaded region satisfies both inequalities.

Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.
