Evan is going to an amusement park. The price of admission into the park is $40, and once he is inside the park, he will have to pay $2 for every ride he rides on. How
much money would Evan have to pay in total if he goes on 15 rides? How much would
he have to pay if he goes on r rides?

70

40+2r

Step-by-step explanation:

x= number of rides

40+2x

plug in 15 for x

40+2(15)

70

for hte other part just replace x with r

40+2r

(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
