6% of what number is 270? 4,500 450 45 4.5
Gnoma [55]

So to solve this problem, we can either do guess and check, or solve an equation.


Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.


So, to begin, let's define our unknown.

We can represent the number as "n"


So, 6 percent of "n" is equal to 270

To find a "percent" of a number, you need to multiply the number by the percentage.

So, 6 percent as a decimal is .06

This is because a percent is a fraction divided by 100 (6/100)


.6\times n=270\\\n=270\div.6\\n= 4500


The number is 4,500

A bank teller has some stacks of bills. The total value of the bills in each stack
Natali [406]
So since only 20 dollar bills and the other one is a 50
then

so we find some combos that will work
five 20's make 100
we notice that we can only have 20's in multipules of 5 to make 100's becauause 4 20's makes 80 and 3 20's make 60 and 2 20's make40 and none of those add to 50 evenly to make 100's
(probably confusing but I hope you understand if you think about it)

so we have
5 20's =100
10 20's=200
15 20's=300
20
25
30
35
40
45 20's=900
50 20's=1000

so how many multiplules did we have?
10
but wait, if we havve 1000 in all 20's we still need at least one 50 so we subtract 100
900:9
answe ris 9 stacks

answer is 9 stacks or A
