Disjunction is a logical operation which forms compound propositions which are false only if all statements (disjuncts) are false. If at least on statement is true the result of disjunction is true. For three statements A, B and C the following table shows how it works (1 means true, 0 means false):
The number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
Given:
<em>Amount with Sam </em>= $2,500
<em>Additional savings each week</em> = $40
<em>Amount with Marshal</em> = $7,300
<em>Amount spent each week</em> = $60
let
x = <em>number of weeks</em>
<em>Sam equation:</em>
2500 + 40x
<em>Marshall's equation:</em>
7300 - 60x
Equate both
2500 + 40x = 7300 - 60x
<em>collect like terms</em>
2500 - 7300 = - 60x - 40x
-4800 = -100x
divide both sides by - 100
x = -4800 / -100
x = 48 weeks
Therefore, the number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
