First of all, you gotta highlight the key things in the question so you know what to do :). 
Secondly, you add both numbers together because it says HOW MUCH so, $1.50 + $21.60 = $23.1 or $23.00.

Therefore, Mary earns $23.00 on Thursday of the same week !! ^_^

Hope this helps !! and have a great and awesome day buddy !! ^_~

Answer:

As per the statement:

On Monday, she earned $21.60.

It is also given that:

Each day, her daily earnings increase by $1.50.

in 1 day = increases by $1.50

then;

in 3 days=increased by [tex]3 \times 1.50 = \$4.50[/tex]

We have to find how much will Mary earn on Thursday of the same week.

She earn on Thursday of the same week = $21.60 + $4.50 = $26.10

Therefore, $26.10 much will Mary earn on Thursday of the same week.
