You go to a restaurant and the bill is 21.86. you need to leave a 20% percent tip and you have $26.00. can you leave a tip? and how much would it be if you left 20%? can you cover the cost

So to find 20% of $21.86, you first need to find 10% and round it to the nearest cent

= $2.186

= $2.19

So you multiply that by 2 to get 20%

=$4.38

To see if you can pay for it, take away $4.38 from $26 and if you have more than $21.86 then you can pay for it.

if not, then you cannot

26.00-4.38 = 21.62

Therefore you cannot afford it
