Answer:

Andrew gets an $11 discount in the taxi but pays $12 each for a tickets
What number of tickets , a , costs Mia and Andrew the same?
Answer:
Maria is a fan of cookie packages, so she has made the calculations and discovered that 4 packages of cookies plus 5 dollars are equivalent to the price of 12 packages of cookies minus 11 dollars.
[tex]a[/tex] represents the price of a package of cookies,
so we have the 4 packages of cookies plus 5 dollars on one side of the equation
[tex]4a+5[/tex]
and on the other side of the equation the 12 packages of cookies minus 11 dollars
[tex]12a-11[/tex]
and if both sides are equivalent we get:
[tex]4a+5=12a-11[/tex]
