Mari,carlos and amanda collect stamps carlos have five more stamps then mari and amanda had three times as many stamps as carlos alyogethey have 100 stamps find the number of stamps each person has

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.
