At the snack bar, a hot dog costs $1.50. This is 60% of the price of a slice of pizza. Which of the following shows both the cost of a slice of pizza at the snack bar, P, and an equation that could be used to find the pizza's cost?

• 0.6(1.50) = P ; P=$0.90

• 0.6P=1.50 ; P = $0.90

• 60p=1.50 ; P= $0.25

• 1.50 = 0.6P ; P=$2.50

Mike is shopping for new clothes. He has a coupon for 20% off of his total purchase. His purchase price before the discount is $68. Let T represent the total cost after the discount. Which equation can be written to model this scenario? SELECT ALL THAT APPLY

• 68-0.2(68) = T

• 68 - .20 =T

• 68-20 = T

• 0.8(68) = T

• 0.2(68) =T

At the snack bar a hot dog costs $1.50 and a slice of pizza costs $2.00. What percentage of the cost of a slice of pizza is the cost of a hot dog?
