Ashley, Bob, and Scott have a total of $95 in their wallets. Scott has 3 times what Bob has. Ashley has $5 less than Bob. How much does each have?

Answer»

Step-by-step explanation:

As per the provided information in the given question, we have :

  • Ashley, Bob, and Scott have a total of $95 in their WALLETS.
  • Scott has 3 times what Bob has.
  • Ashley has $5 less than Bob.

We are asked to calculate how much does each have.

Let us suppose the share of Bob as X. According to the question, Scott has 3 times what Bob has. Writing the expression of the share of Scott in the terms of Bob's share :

\longrightarrow \sf{\quad { Scott's \; share = <klux>3X</klux>}} \\

Also, according to the question, Ashley has $5 less than Bob. Writing the expression of the share of Ashley in the terms of Bob's share :

\longrightarrow \sf{\quad { Ashley's \; share = (x - 5) }} \\

Now, we have been given in the question that Ashley, Bob, and Scott have a total of $95 in their wallets. So, according to this STATEMENT we can conclude that the sum of the share of Ashley, Bob, and Scott will be $95. Writing it in the FORM of a linear equation,

\longrightarrow \sf{\quad { (x - 5) + x + 3x = \$ \; 95 }} \\

Remove the brackets in the LHS.

\longrightarrow \sf{\quad { x - 5 + x + 3x = \$ \; 95 }} \\

Performing addition of the like terms in LHS.

\longrightarrow \sf{\quad { - 5 + 5x = \$ \; 95 }} \\

Transposing – 5 from LHS to RHS, its sign will get changed.

\longrightarrow \sf{\quad {5x = \$ \; 95 + 5 }} \\

Performing subtraction in RHS.

\longrightarrow \sf{\quad {5x = \$ \; 100 }} \\

Transposing 5 from LHS to RHS, its arithmetic operator will get changed.

\longrightarrow \sf{\quad {x = \$ \; \cancel{\dfrac{100}{5}} }} \\

Dividing 100 by 5.

\longrightarrow \quad { \textbf{\textsf{x}} = \sf \$ \; \textbf{\textsf{20}}  }\\

\underline{ \qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad} \\

Therefore,

  • Ashley's Share : (x – 5) = $(20 – 5) = $15
  • Bob's Share : x = $20
  • Scott's Share : 3x = $ 3(20) = $60
