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.

$7.05
Step-by-step explanation:
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %

x=8
Checking work)
2(8)-2=14
16-2=14
14=14
