Respuesta :
Mari: M
Carlos: M + 5
Amanda: 3(M + 5)
Total: 100
Mari + Carlos + Amanda = Total
M + M + 5 + 3(M + 5) = 100
2M + 5 + 3M + 15 = 100
5M + 20 = 100
5M = 80
M = 16
Carlos (C): M + 5 = (16) + 5 = 21
Amanda (A): 3(M + 5) = 3(16 + 5) = 3(21) = 63
Answer: Mari=16, Carlos=21, Amanda=63
The number of stamps each person has will be Mari=16, Carlos=21, and Amanda=63.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that Mari, Carlos, and Amanda collect stamps Carlos has five more stamps then Mari, and Amanda had three times as many stamps as Carlos altogether having 100 stamps.
The number of stamps each person will be calculated as:-
Mari: M
Carlos: M + 5
Amanda: 3(M + 5)
Total: 100
Mari + Carlos + Amanda = Total
M + M + 5 + 3(M + 5) = 100
2M + 5 + 3M + 15 = 100
5M + 20 = 100
5M = 80
M = 16
Carlos (C): M + 5 = (16) + 5 = 21
Amanda (A): 3(M + 5) = 3(16 + 5) = 3(21) = 63
Therefore, the number of stamps each person has will be Mari=16, Carlos=21, and Amanda=63.
