Question

Jessica and Raphael are saving money for concert tickets. Jessica has $20 and saves 10 per week.

Jessica came up with the following equation to figure out how much money she saves for any given week.

y=10x+20

Raphael has $40 and saves $6 per week.

Raphael created a table to show how much money he saves each week.

Weeks 0 1 2 3 4 5 6 7 8
Amount Saved 40 46 52 58 64 70 76 82 88
After saving for a certain number of weeks, Jessica and Raphael will have each saved the same amount of money.

How much money will they have each saved then?

Answer 1

They have the same amount on week 5 ($70)
The Answer would be: $70
((Got this correct on my quiz, If you need it explained, It is below))
The easiest way to do this is to not pay attention to the y=x equation, because the solution is already in the information, this may confuse you and youre wasting time to solve it. Jess has $20 BEFORE saving and gets $10 WEEKLY, Raph has $40 BEFORE saving and gets $6 WEEKLY. In the chart/information, add the amount it takes to get Jess up to $40 then add $10 for every week on going until both their balances are equal. They match on the 5th week with $70 // If the information is different substitute the names/numbers/etc. Hope this helped you and anyone else looking for the answer!
