Tomas used incorrectly the rule of signs, the expression should be simplified as follows:
-2.6 + (-5.4)
-2.6 -5.4 = 8

What mistake did Tomas likely make?</h3>
Here Tomas wants to perform an addition between two numbers:
-2.6 + (-5.4)
And the outcome that Tomas gets is:
-2.6 + (-5.4) = 2.8
Here his mistake seems to bee that he thought the second number was a positive number, and he solved the operation:
-2.6 + 5.4
So, he used wrong the rule of signs.
Remember that the rule of signs says that:
(-)*(+) = (+)*(-) = (-)
Using that, we can rewrite the original expression:
-2.6 + (-5.4)
to:
-2.6 - 5.4
Solving that, we get:
-2.6 - 5.4 = -8
Which is the outcome that Tomas would have gotten if he had used correctly the rule of signs.

The amount earned by Robin is $224
- Given the cost of 182-day T-bill = $160,000
If Robin is discounted to yield 1.96%, the amount yield is expressed as:
The yield of 1.96% = 1.96% of 160000
The yield of 1.96% = 0.0196 * 160000
The yield of 1.96% = $3136
Similarly, if the yield is dropped to 1.82%
The yield of 1.82% = 1.82% of 160000
The yield of 1.82% = 0.0182 * 160000
The yield of 1.82% = $2,912
Amount earned by Robin = $3136 - $2192
Amount earned by Robin = $224
Hence the amount earned by Robin is $224

Hello!

Good luck!
Point? I'm pretty sure or the origin point
You can recognize exponential and linear functions by their graph. Linear functions are straight lines while exponential functions are curved lines. You can also recognize them by the change in y. If the same number is being added to y, then the function has a constant change and is linear
