`\LARGE{ \underline{\underline{ \tt{Required \: answer:}}}}`

We have,

• Initial amount = $125 (Constant)
• Per week savings = $40
• Amount to be collected for buying a PS5 = $600

What to do?

• We need to frame an equation with variable determining the no. of weeks it will take him to save up the money.

Here's how to do?

Let the no. of weeks be x. Then,

Amount collected by savings = $40x

So, The equation will be:

➝ 125 + 40x = 600

Note:

• Don't forget to add the unit i.e. dollars '$' here.
