Answer:
27% of change
Explanation:
If you get a calculator type in 400 multiplied 73% you get $292. Its not the exact answer because there is no exact answer for this but..... There is always tax you have to pay for an item and so here Anthony would have to pay $3 for tax.
If 27% is not one of the answers the other answer that is possible is 30% and you would get a total of $280 and pay $15 for taxes.
Hope this helps :)
