Answer:
$2.70
Step-by-step explanation:
To calculate this you could use 2 ways.
1) The first method is to use the multiplier method.
To Calculate this you would multiply 3 by 0.9. This is because you are reducing the amount by 10%.
1)Multiply $3.00 by 0.90.
[tex]3*0.90=2.7[/tex]
2) The second method is to first find 10% and then minus that from $3.
The formula to calculate the percentage is to divide the percentage by 100 and multiplying it by the number.
1) Divide 10 by 100.
[tex]10/100=0.1[/tex]
2) Multiply 0.1 by 3.
[tex]0.1*3=0.3[/tex]
3) Minus 0.3 from 3.
[tex]3.00-0.3=$2.7[/tex]
