I disagree with her because for every 1 is six, it shouldn’t have +y on it that is just adding a number that is unneeded
1 joule = 6,242e+18ev
20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev
1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.
1% of $32K is $320
5% of $32K is $1600
$1600 + $320 = 6%
TOTAL IS $1920
