Question

Yasmine works as a server in a restaurant and earns different amounts in tips each night. Her range of earnings in tips over the course of 8 nights of work is $86.33. Her tip earnings are listed in order from least to greatest, with one missing.

$10.45, $20.50, $35.80, $38.10, $40.87, $45.90, 79.60, ______

What tip earning value is missing?

Answer 1

Range = maximum − minimum. The minimum is $10.45, so the maximum = $10.45 + $86.33 = $96.78. Thus the missing value is $96.78.
