John needs to replace his shoes so he decides to buy a $150 pair of Nikes and a $120 pair of work boots.  Tax is 10%.  How much did he pay for everything?
How much did the shoes cost? ** The shoes cost $150 + $120 = $<<150+120=270>>270
How much did the tax cost? ** The tax was $270 * .1 = $<<270*.1=27>>27
How much did John pay for everything? ** So the total cost was $270 + $27 = $<<270+27=297>>297
