Step 5: Answer in a complete sentence

He took 30 weeks to save $ 500

Step-by-step explanation:

Let 'x' be the number of weeks

Money deposited after each week = $ 15

Money deposited 'x' weeks = 15 * x = 15x

Opening balance in his account = $50

So, money that will be in his account after x weeks =  50 +15x

Total money in the bank = $500

50 + 15x = 500

       15 x = 500 - 50 { Subtract 50 from both sides}

        15x = 450   { Divide both sides by 15}

     15x/15 = 450/15

x =  30 weeks
