Yolan buys 8 pens and receives 80 cents change from $20.00. How much does a pen cost, assuming each pen costs the same amount? btw ik Yolan is getting ripped off
Subtract the change from $20.
$20-0.80=$19.20.
Divide $19.20 by the amount of pens Yolan bought.
$${\frac{{\mathtt{1\,920}}}{{\mathtt{8}}}} = {\mathtt{240}}$$
Move the decimal one point, resulting in 2.40
Each pen cost Yolan $2.40
Good work Rubenhh
