A newsstand spends $600 a month on rent and electricity, and it spends $1.50 for each magazine that it sells. The newsstand charges $6 for each
magazine. If nis the number of magazines, which equation represents the
profit function of the newsstand?
O A. p= 6n-600
O B. p= 4.50n- 600
OC. p= 1.50n + 600
OD. p= 600n+4.50

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
