EXAMPLE 1 Standardized Test Practice SOLUTION Substitute several values of h into the equation C = 10 + 7h and solve for C.Then identify the table that contains the solutions.

EXAMPLE 1 Standardized Test Practice h -value Substitute for h. Evaluate. Solution (h, C) h = 1C = 10 + 7(1) h = 2 h = 3 h = 4 C = 10 + 7(2) C = 10 + 7(3) C = 10 + 7(4) C = 17 C = 24 C = 31 C = 38 (1, 17) (2, 24) (3, 31) (4, 38) ANSWER The correct answer is C.

GUIDED PRACTICE for Example 1 What If? In Example 1, suppose the store rounds your time up to the nearest half hour. How long can you skate if you have \$35 ? 1.1. ANSWER You can skate for 3.5 hours or less.
