Jonathan has $10 that he earned from selling candy at school. He goes to the store in hopes of buying a baseball card that costs $8.50, but is on sale for 20% off. What is the price he has to pay? How much money will he have left?
20% of 8.50 is 1.70. 8.50-1.70= 6.80, Therefore the final price will be $6.80. His change will be $10.00-6.80 = $3.20
