Just need to convert the mass of moon in terms of 10^24. So shift over 2 decimal places.

5.97 x 10^24 + 0.0734 x 10^24 = 6.04 x10^24

A school bake sale eared over $25 from selling cookies, $3 each how many cookies did they sell

MAXImum [283]

For $25 exactly is 8.3 cookies (recurring 3) but that is highly unrealistic, so over 25 dollars is 9 cookies (for 27 dollars) at the very least.
