TRAVIS AND PAULA SPEND FOR LUNCH 7.50+5.25=12.75 DOLLARS
WE NEED TO FIND OUT HOW MUCH IS 1% OUT OF 12.75 WHICH IS 
12.75/100=.1275
.1275*15=1.91 TIP LEFT 
12.75+1.91=14.66
Subtotal: 7.50 + 5.25 = $12.75
Tip = 0.15(Subtotal)
Total = Subtotal + Tip = Subtotal + (0.15)Subtotal = 1.15(Subtotal) = 1.15(12.75) = 14.6625 --> Choice B ($14.66) is the closest
