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.
Let
x-------> the whole number
y------> the decimal number
we know that
------> equation 1
assume the value of x and then calculate the value of y
Let
x=280
solve for y in the equation 1

substitute the value of x


therefore
<u>the expression is equal to</u>
280*0.001=0.28
