Chapter 2.3: Question #16


Boris has 2 1/2 times as much cash as Anna. Charlie has 3/4 as much cash as Anna. Anna has $25.60 in cash.

a)How much cash do the three people have altogether?

b)How much more cash does Boris have than Charlie?


a) The three people have $108.80 all together.

1) First I multiplied 2 1/2 by 25.6o.

2) Second I multiplied 3/4 by 25.60

3)Then for question a) I added how much Boris had, which was $64, then added how much Charlie had, which was $19.20, then lastly I added how much Anna had, which was $25.60.

b) Boris has $44.80 more than Charlie.

1) I used the answers i got from question a) for question b).

2) I subtracted what Charlie had, which was $19.20, from what Boris had, which was $64.
