Alex gets paid $2.25 a tree for tree planting up north. In one week, he planted 437 trees. What is his wage?
Amiraneli [1.4K]

Answer:

Hey Beebzie

Dang he part of 20m trees? And is Alex a he or she, we'll never know, so I'll just refer to Alex as "it" to not gender appropriate anyone.

So it gets paid 2.25 for one tree. It planted 437 tress.

We take 2.25 x 437 to know the amount of money earned for all trees it planted.

The answer is $983.25, or A. I don't want to gender appropriate the letter "A" either because it could be option 1 or a different letter so I'll just say the answer again to not be sexist, $983.25
