Answer :

To translate the sentence into an equation, follow these steps:

1. The phrase "240 decreased by [tex]$j$[/tex]" means that we start with [tex]$240$[/tex] and subtract [tex]$j$[/tex], which gives:
[tex]$$240 - j$$[/tex]

2. The phrase "is equal to 218" means that the expression we wrote is equal to [tex]$218$[/tex], so we set up the equation:
[tex]$$240 - j = 218$$[/tex]

Thus, the final equation is:

[tex]$$240 - j = 218$$[/tex]
