CDs now cost $11 each and cassettes now cost $7 each. Write an expression for the new total amount you will spend. Then evaluate the expression when 6 of the people get CDs.

Answer 1

Answer:

For 10 people:

Cost CD'S: 10 x 11 = 110

Cost Cassettes: 10 x 7 = 70

Total Cost = 110 + 70 = 180

For 6 people:

Cost CD's: 6 x 11 = 66

Cost Cassettes: 6 x 7 = 42

Total Cost = 66 + 42 = 108
