Carly mowed 2 more lawns than Rocco each week for 6 weeks. Carley mowed a total of 18 lawns. How many lawns did Rocco mow each week?

Rocco mowed 1 lawn a week.

You wanna divide Carley’s total mowed lawns by the amount of weeks she mowed for.
18/6 = 3
Carley mowed 3 lawns a week.
We’ll take away two from that because she mowed two more that Rocco each week, resulting in Rocco mowing one lawn a week.
Hope this helps!! :))
