18. 10. Samuel and Joyce both bought CDs. Samuel bought 3x CDs and Joyce bought 2x-1 CDs. If each CD had a regular price of \$18 and a discount of \$2, then which expression would show the amount of discount for all of their CDs? The total number of cd’s The discount was \$2 per cd, Christopher Collins - Leto High School

19. What is the expression for the COST of their CDs, combined? (ignore tax) The total number of cd’s The price of cd’s were \$18-\$2 = \$16 apiece Christopher Collins - Leto High School

20. 11. Match the statement with the equation: (Choices are below) • Her salary is one dollar more than twice John’s salary. • B. John’s salary is twice hers plus \$1. • C. Twice John’s salary is the same as her salary plus one. • D. Twice her salary is the same as John’s salary plus \$1. Choices: 1. 2H=J+1 2. H=2J+1 3. 2J=H+1 4. J=2H+1 Christopher Collins - Leto High School
