Mason counted an average of 18 birds at his bird feeder each day for 20 days, Gloria counted an average of 21 birds at her bird feeder each day for 16 days. How more more birds did Mason count at his feeder than Gloria counted at hers? Birds counted by Mason: 18 times 20 = 360 Birds counted by Gloria: 21 times 16 = 336 Draw a bar model to compare. Subtract. 360 - 336 = 24 The 24 students in Ms. Lee's class each collected an average of 18 cans recycling. The 21 students in Mr. Galvez's class each collected an average of 25 cans for recycling. How many more cans were collected by Mr. Galvez's class than Ms. Lee's class?Explanation / Answer
Number of Cans collected in Mr Lee's class = Number of students in Mr Lee's class * number of average cans collected by each class
=> 24 * 18 = 432 cans
Number of Cans collected in Mr Galvez class = Number of students in Mr Galvez class * number of average cans collected by each class
=> 21 * 25 = 525 cans
More number of Cans collected = 525 - 432 = 93 cans
