The Baptist family goes out for lunch, and the price of the meal is $45. The sales tax on the meal is 6%, and the
family also leaves a 20% tip on the pre-tax amount. What
is the total cost of the meal?
O $56.70
O $71.87
O $57.24
O $65.37

$56.70

Step-by-step explanation:

45.00(0.06) = 2.70

45.00(0.20) = 9.00

45.00 + 9.00 + 2.70 = $56.70

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
