You can put this solution on YOUR website!

let tax be x% orx%2F100
given price p=+2375pesos and total bill 2530pesos
you need to find x% (or x%2F100) of p=2375pesos, add it to the p to get the total bill of 2530pesos
so,
2375pesos%2B%28x%2F100%292375pesos=2530pesos
%28x%2F100%292375pesos=2530pesos-2375pesos
%28x%2A2375pesos%29%2F100=155pesos
x%2A2375cross%28pesos%29=15500cross%28pesos%29
x=15500%2F2375
x=6.526315789473684
x=6.53% is the sales tax rate
