Answer:

Martha earns $65.6 over the weekend.

Step-by-step explanation:

Brownies sold by Martha on Saturday = 60

Cookies sold by Martha on Saturday = 42

Brownies sold by Martha on Sunday = 28

Cookies sold by Martha on Sunday = 54

Total brownies sold by Martha over the weekend = $60+28=88$

Total cookies sold by Martha over the weekend = $42+54=96$
