Question

In a certain video game, players earn bonus points after finishing a

level. The number of bonus points is based on how many seconds, t,
it takes the player to finish the level. The game uses the expression
-5.5 + 500+ 0.9t + (1 - 1.9t to determine the number of bonus points. .
Zahara finishes a level in 201 seconds. How many bonus points does she earn?

Answer 1

If Zahara finishes a level in 201 seconds, she earns:

• 294.5 points

Explanation:

To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:

• -5.5 + 500+ 0.9t + (1 - 1.9t)

Where:

• t = time in seconds.

As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:

• -5.5 + 500+ 0.9t + (1 - 1.9t)
• -5.5 + 500+ 0.9(201) + (1 - 1.9[201]) (we're not use the unit "seconds", because we don't need it in this calculation)
• -5.5 + 500+ 180.9 + (1 - 381.9)
• -5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)
• 500 + 180.9 - 380.9 - 5.5
• 294.5 points

As you can see, Zahara obtains 294.5 points if she finishes the level in 201 seconds.
