Three persons had dinner in a restaurant. The total bill came to $51.60.
SVETLANKA909090 [29]

Answer:

Each person tipped $4.30.

Step-by-step explanation:

We know that the total bill was $51.60. The three people paid a 25% tip, which was split evenly among them.

Since the tip is 25%, it will be 25% of the total. Hence:

0.25(51.6) = \$ 12.9

The total tip is $12.9.

And since it was evenly split among three people, each person tipped:

\displaystyle \frac{12.9}{3}=\$ 4.30

Each person tipped $4.30.

Carly is saving money by babysitting on the weekends. Last month, she saved $120.
DENIUS [597]
$156.
you would change the 30% to a decimal by moving the decimal point two spaces to the right.
this would get you .30 or .3
you would then multiply the $120 by .3
you would get 36
then since she saved 30% MORE you would add the 36 to the 120 and get 156
