The answer is going to be 12.9 and the median height will be 16.5 hope that helped
A=P(1+rt)
A/P=1+rt
A/P-1=rt
AP-P/Pr = t
A-1/r=t
X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)
From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)
Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.
Cos35= y/15
y= 15cos35
y= 12.3 cm
15x = 292.50
Divide 15 from both sides
X= 5.85
1 T-shirt = $5.85
45x = 747.50
Divide 45 from both sides
X= 16.61
1 T-shirt = $ 16.61
