Jenny is making sandwiches, it takes her 8 minutes to make 3 sandwiches. how long will it take her to make 7?
Estimate to reach the answer.
i was just being lazy, but when i did the work i found the answer was 15 =b
thanks for the help though. i used your estimate to estimate a different answer XD.
As an estimate, it will take her about 18 minutes....
as a true number it will take her 8/3 min/sand x 7 sand = 56/3 = 18.67 min
