Answer:
53.52°
Step-by-step explanation:
cos x° = 22/37 = 0.59456
x = 53.52°
Let x = the cost of the student discount card.
x + the cost of the passes = 29.50
x + 15(1.50) = 29.50
x + 22.50 = 29.50
Subtract 22.50 on both sides to isolate the variable x.
x = 29.50 - 22.50
x = 7
The student discount card is $7.
