Answer:
$15.60
Step-by-step explanation:
We can solve this problem easily by adding up Miguel's expenses, and then subtracting them from the amount he started with. Be careful, as he pays $4, not $2, in total for bus fare, because he is paying $2 to and from:
[tex]6.75+3.65+4.00[/tex]
[tex]=14.40[/tex]
Let's subtract our sum, [tex]14.40[/tex], from our total, [tex]30[/tex]:
[tex]30-14.40[/tex]
[tex]=15.60[/tex]
Miguel has $15.60 left.
