110x + y = 1,210. A coffee shop is running a promotion where a number of free coffee samples are given away each day. The equation can be used to
model the number of free coffee samples, y, that remain to be given away
x days after the promotion began. How many total coffee samples will the
coffee shop give away?*

Y = 1210 - 110X

In X days, The number of free coffee will be given

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
