Let, number of burritos Dave’s Wraps sell today= x

(1) A total of 350 burritos was sold at Dave’s Wraps yesterday, which is 100 fewer than twice the number sold today.
350=2x-100
2x=450 ; x=450/2=225
Sufficient

(2) The number of burritos sold at Dave’s Wraps yesterday was 20 more than the number sold today.
Yesterday= 20+x
Insufficient
