Answer 1

M, C, A are the numbers of stamps Mari, Carlos and Amanda each have.

C=M+5, A=3C=3M+15.

M+C+A=100; M+M+5+3M+15=100; 5M=100-20=80, so M=16, C=21, A=63.

Answer 2

Mari, carlos and Amanda collect stamps. Carlos have fime more stamps than mari, and amanda has 3 times as many as carlos. Altogether, they have 100 stamps. Finde the number of stamps each person has.

There is some information missing from your question.

You say: "Carlos has fime more stamps than Mari"

I am assuming that this should read, "Carlos has five more stamps than Mari"

Let M be the number of stamps Mari has.

Let C be the number of stamps Car;ps has.

Let A be the number of stamps Amanda has.

Then,

M + C + A = 100             (Altogether, they have 100 stamps)

M + 4C = 100                 (amanda has 3 times as many as carlos)

M + 4(M + 5) = 100        (Carlos has five more stamps than Mari)

5M + 20 = 100

5M = 80

M = 16, C = 21, A = 63
