The Perez family went out to dinner. The price of the meal was $39.75. The sales tax was 7% of the price of the meal. The tip was 15% of the meal and the sales tax. How much money did the Perez family pay for the meal, including tax and tip?

$48.91

Step-by-step explanation:

100% is 1 so 7% would be 0.07

times $39.75 by 0.07 to get the amount the tax would add which is $2.78

then add the two $39.75 + $2.78 = $42.53

then remove the tip which as we saw earlier convert the 15% to 0.15

times $42.53 by 0.15 to get the amount the tip would add which is $6.38

then add $6.38 to the total amount which would be $48.91
