Izzy wants to raise money for new equipment by selling t- shirts. he pays $5.30 for each t-shirt and needs to raise $465 above the total cost of the t'shirt . if 75 students order t-shirts, by what percent must izzy mark up the t-shirts to raise $465 above the total cost of t-shirts?

Ok so this is gonna get a little confusing:

So he buys 75 shirts @ $5.30/shirt = $397.50

He has to make $465 above the $397.50 which equals $862.50

That 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

Just a second zzz
