Answer: $ 205

Step-by-step 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

[tex]\dfrac{x}{10}=\dfrac{143.50}{7}\\\\\Rightarrow\ x=\dfrac{143.50}{7}\times10=\$205[/tex]

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