\huge \fcolorbox{black}{red}{Answer:-}

Ok so this is gonna get a little confusing:

so he buys 75 shirts $5.30/shirt = $397.50he has to make $465 above the $397.50 which equals $862.50that means that to make the amount needed, he would have to sell each shirt $11.50/shirt

$5.30/$11.50= .4608695. meaning that the shirts would have to be marked up roughly 46.09% for izzy to make the $465 above the cost of the shirts
