Each month for 7 months, samuel mows 3 lawns. how many more lawns does he need to mow before he has mowed 29 lawns.

i think it is 8 more lawns and not 7.
7x3=21; 29-21=8.

am i wrong?

No,  He needs to to mow 7 more lawns before he has mowed 29 lawns.

The number of months he mowed the lawns = 7

Then, the number of lawns mowed by Samuel =

Let x be the number of  lawns he needs to mow before he has mowed 29 lawns, then x<29

The number just before 29 is 28

Then,

Hence, he needs to to mow 7 more lawns before he has mowed 29 lawns.
