coupon that will take 1/10 off the sale price. There is no sales tax on clothing. If Allison pays with a $50 bill, how much change will she receive? (Note: Express the answer as dollars.cents.)
Add all of the sides together. Make sure to use a common denominator because you are adding fractions. Don't forget your unit label (feet) + + + + feet
