Hello,

100% ---> \$80.00
10% ----> \$8.00
50% ----> \$40.00

The reduced price at 10% off is now \$72.00 and the reduced price at 50% off is \$40.00.
The statement of Heather's friend is therefore partly wrong.

yah, may be she can get it.
Heather friend is appoximately correct
because the percentage is 10%to 50%
cost price =\$80
Percentage for 10%=\$80*10/100=\$8,that means \$80-\$8=\$72
Percentage for 20%=\$80*20/100=\$16,that means \$80-\$16=\$64
Percentage for 30%=\$80*30/100=\$24,that means \$80-\$24=\$54
Percentage for 40%=\$80*40/100=\$32,that means \$80-\$32=\$48
Percentage for 50%=\$80*50/100=\$40,that means \$80-\$40=\$40
Now u may understood the percentage
