Tat weekend, 72 of the cans sold. What percent of the

Answer 1

Take your original value which is 150 and multiple it by your percent.

Answer 2

You can easily turn a percent into a decimal by multiplying it by .001

Answer 3

.01*

Answer 4

Knowing this, what do you think the answer is?

Answer 5

I want to say D because when I multiplied 72 with 0.1 it came out as 7.2

Answer 6

Here, lemme work through it with you.

Answer 7

I will tell you the correct answer is C

Answer 8

\[150+x%=72 \]

Answer 9

x%=72

Answer 10

Multiply 2 by .01

Answer 11

it's 0.2

Answer 12

.02*

Answer 13

Now multiply .02 by 150

Answer 14

Okay, ( using a calculator btw) I get 3

Answer 15

Right, 3 is not 72.

Answer 16

So if 2 was 3 then it is logical that 5% would not equal your 72

Answer 17

What is 48*.01

Answer 18

0.48

Answer 19

Multiply 150 by .48

Answer 20

72
