Andréa and Marta are testing three different coolers to see which keeps the coldest temperature. They placed a bag of ice in each cooler, closed the coolers, and then measured the air temperature inside each after 90 minutes. The temperatures are recorded in the table below:

Cooler A B CTemperature (ᵒC) −2.91 5.7 −4.3

Marta wrote the following inequality statement about the temperatures:−4.3←2.91<5.7.

Andréa claims that Marta made a mistake in her statement and that the inequality statement should be written as

−2.91←4.3<5.7.
