You need to first add up the total cost which is 12.45, then find 6% of 12.45 which is .747 or rounded to.75.(tax) then you need to add it to get 13.20. so the tip was 13.20
<h3>(1136+1272)-(1138+{-1250})</h3><h3>=2408-(-112)</h3><h3>=2408+112</h3><h3>=2520</h3><h3>the answer is 2520</h3><h2 /><h2 /><h2>hope it helped :-)</h2>
