A restaurant adds a 20% tip to the bills of parties of 6 or more people. Suppose a server waits on five such tables. The bill
castortr0y [4]

Answer:

$218.70

Step-by-step explanation:

You need to first convert the percentage to the decimal.

20% = 0.2

Now, you need to find 20% of each bill by multiplying each bill by 0.2.

0.2(185.45) + 0.2(205.20) + 0.2(195.05) + 0.2(245.80) + 0.2(262.00)

Because of the distributive property, you can add up the bills and multiply the sum by 0.2.

0.2(185.45 + 205.20 + 195.05 + 245.80 + 262.00)

0.2(1093.50)

218.7

The waiter made $218.70 in tips.

Find the quotient simplify your answers a+3 over a divided by 8 over a
mihalych1998 [28]
ANSWER

\frac{a + 3}{8}



EXPLANATION

We want to simplify

\frac{a + 3}{a}  \div  \frac{8}{a}


We multiply the first fraction by the reciprocal of the second fraction to obtain,



\frac{a + 3}{a}   \times  \frac{a}{8}


We cancel the common factors to get,


\frac{a + 3}{1}   \times  \frac{1}{8}

This gives us,

\frac{a + 3}{8}
