Two instant camera cost 2 x $110 = $<<2*110=220>>220.
Three digital photo frames cost 3 x $120 = $<<3*120=360>>360.
Thus, the total amount is $220 + $360 = $<<220+360=580>>580.
So, Selena gets a discount of 5/100 x 580 = $<<5/100*580=29>>29.
Therefore, Selena pays a total of $580 - $29 = $<<580-29=551>>551.
