First of all, her budget is $29.5 .. 
Whatever she does, she has to pay $19 .. 

So, the remaining thing would give you the amount that she could use .. $(29.5 - 19) = $10.5

It is given that she is charged $0.07 per minute.. 

now use unitary method .. i.e 

$0.07 ---> 1 minute
$1 ------> 1/0.07 minutes
$10.5 ---> ?
