The jackson family went out to dinner. the price of the meal was $43.45. 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 smith family pay for the meal, including tax and tip?

$53.46

Step-by-step explanation:

If the meal was $43.45 and there is a sales tax of 7% then we can think of it as 100% of the meal plus 7% therefore 100%+7%=107%.  Since 107% is equal to 1.07 in decimals the meal plus the sales tax is:

Now the Jackson family is going to tip 15% on the meal and sales tax, meaning $46.49 + 15%.  Similar to above 100% + 15% = 115% = 1.15.  And so:

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09
