The Jackson family went out to dinner

vovikov84 [41]

Answer: Amount that the Smith family need to pay for the meal including tax and tip = 53.47.

Step-by-step explanation:

Since we have given that

Price of the meal = 43.45

Rate of sales tax = 7%

Amount becomes after the sales tax is given by

$\frac{7}{100}\times 43.45\\\\\frac{304.15}{100}\\\\=3.0415\\\\\text{Amount}=43.45+3.0415=46.4915$

Rate of tips over meal and sales = 15%

Amount of tips is given by

$\frac{15}{100}\times 46.4915\\\\=0.15\times 46.4915\\\\=6.974$

So, Amount becomes

$46.4915+6.974\\\\=53.465\\\\=53.47$

Hence, Amount that the Smith family need to pay for the meal including tax and tip = 53.47.

Anika [276]

Answer:
58.5 mg
