Answer: $ 205

Explanation:

Let x be the amount (in dollars) of money she will earn by mowing 10 lawns.

Given : Mia's weekly income varies directly with the number lawns she mows.

She earns $143.50 mowing 7 lawns .

Then by using proportionality , we have


(x)/(10)=(143.50)/(7)\\\\\Rightarrow\ x=(143.50)/(7)*10=\$205

Hence, she will earn $ 205 if she mows 10 lawns.
