According to the given data we have the following:
hair bans Sue already owns=35
additional hair bands= 2 for a dollar
$2 to spend on new hair bands
Therefore, In order to calcilate the total hair bands can Sue own we would have to make the following calculation:
additional hair bands=$2*2=4
Therefore, total hair bands can Sue own=35+4
total hair bands can Sue own=39
Therefore, Sue would own as total 39 hair bands.
