Question

Jack and his friends are collecting cans for the food bank. Thus far, they have collected 1500 cans. Jack has collected 60 percent of the cans. Marcia has collected 25 percent of the cans. How many cans have their other friends collected thus far?

Answer 1

multiply 1500 by .6, so jack collected 900. multiply 1500 by .25, so Marcia collected 375, so the other friends collected 225 cans, because 1500 - 1275 is 225

Answer 2

1500*.6=900, 1500-900=600, 1500*.25=375, 1500-375=1125, 1125-900=225, so the remaining friends have collected 15% of the cans which is a total of 225 cans. Explanation is that we start by finding how much 60% is of 1500 which is 900 now that we have that we need to subtract 900 from 1500 like so which equals 600, now we need to see how much 25% is of 1500 which is 375 then youll take 1500-375=1125 then take 1125-900=225, leaving you with 225 cans that your other friends picked up and then you take 100-60-25=15% so your friends picked up 15% of the remaining cans which is a total of 225 cans.
