Jamie builds chairs and tables in her shop. It takes her 2h to make a chair and 7h to make a table. Jamie works 60 h a week. She made 4 tables last week.

Question

1. Write an equation that describes this situation. Include a "LET" statement.
2. Solve the equation to find the number of chairs she made last week.

Answer 1

7 hours to make a table

4 tables take 7x4 = 28 hours

60 hours - 28 hours is 32 hours making chairs, 2 hours per chair means 32/2 = 16 chairs

16 chairs take 16x2 = 32 hours

Let H = hours, T= number of tables, C=number of chairs

H= 7T + 2C

60 =7(4)+ 2(16) = 28+32
