Question

To enter a competition, students must score a total of at least 450 points on five qualifying tests. Each test is worth 100 points. On the first four tests, your scores were 94, 88, 79, and 95. What are three possible scores you can earn on the last test to enter the competition?

Answer 1

Data

450 points on five qualifying tests

Each test is worth 100 points.

94, 88, 79, and 95

Process

Subtotal score = 94 + 88 +79+95

Subtotal score = 356

Last test

LT = 450 - 356

LT = 94 points at least

Possibles scores = 95, 96, 97

The inequality would be

`\begin{gathered} LT\ge450-356 \\ LT\ge94 \end{gathered}`

Where LT = the Last test
