Well you can easily calculate 10% just by moving the decimal 1 place to the left to get 3.5

Then for 20% you would double this amount: 3.5 + 3.5 = 7

So your tip amount would be $7.00.

good luck!

20% of 35
therefore
20/100*35
=7$

first turn the 20% into a decimal by dividing by 100. that gives you .2 . Then just multiply times 35. That gives you 7.

let x be the tip u have to give .........(1)
the cost of the meal =$35
so your answer would be
=> x/$35*100=20%
=>x=(20*35)/100
=>x=700/100
=>x=$7 : answer

20% of $35 = .2($35) = $7.00
Dinner + tip = 35+7 =$42.00

.2*35 so 1/5*35=7... which is the tip

20% tip means 20% of $35
so we find (20/100) * 35
=$7
if the total cost is required , add 7 to 35.
So it becomes $42

20% of 35;
the q wants us to find WHAT SHOULD WE pAy IF $35 is dived equally to 100 parts out of which U need to pay 20 parts extra as a tip;

step 1 divide 35 into 100 equal parts;
assign 100 parts of something(s,say)=35
1 part of something(s)=35/100
1 part of something(s)=35/100
1 part of something(s)=35/100
1 part of something(s)=35/100
....
adding them 20 times(as asked in the question)
20 parts of something(s)=35/100+...(20 times)
=20(35/100)
hence I should pay $7 as tip.

Simple ....

what is 20% of $35

i.e. (20/100) of $35
=(1/5)*35
=$7
So you should have a sum of $42 in your hands to eat,if you don't just cook yourself or starve for a day.....

I used a slide rule in college. You would multiply 2 times 35 and get 70. Move the decimal one place since it is .2 not 2. In other words: $7.00.

For 15%, which is what I often pay, you break it into two parts. You would pay 10% + half of 10% = 15% so

10% => 3.50
+ 5% => 1.75 (half of 10%)
------------------------------------------
15% => $5.25

So you are more generous and pay 20% or $7.00.
