Astore pays $120 for a television. the store sells the television for $300. your classmate says that the markup is 150% because $180$120=1.50$180$120=1.50. is your classmate correct?

Your class mate is correct. Remember when multiplying by a percentage to move the decimal place 2 decimal places to the left. Because 120 and 180 are equal to 300 your classmate is correct in saying that the mark up is 150%
