Answer:
46
Step-by-step explanation:
Let the amount of stamps Mari has be “m”. Since Carlos has 5 more stamps than Mari, Carlos will have 5+m stamps. Amanda has three times as many stamps as Carlos so that will be 3(5+m)=15+3m.
m+(5+m)+(15+3m)=100
5m+20=100
5m=80
m=16
Mari=16
Carlos=16+5=21
Amanda=15+48=63
