Jennifer is saving money to buy a bike. The bike costs $210. She has $126 saved, and each week she adds $14 to her savings. How long will it take her to save enough money to buy the bike?

If the bike costs $210 and she has $126 saved and adds $14 from her saving, then she need $84 to get the exact amount of the bike. What I did was I divide 84 to 14 and I got 6 weeks.

Hi there.

Thanks for using Brainly today. Hope all is well!

Let:

x = number of weeks

So, x = 14 since that's the amount every week.

Great! We know the value of x.

Let's set up the equation.

The cost is the = to the equation, so it goes at the end.

$126 is saved, and will be at the start.

14x is the weeks, and will be after the 125 to represent the weeks.

So, our equation:

126 + 14x = 210

Now -- we can solve:

126 + 14x = 210

-126 -126 (Subtracting -126 from both sides to get x by itself)

14x = 84

Divide 84 into 14:

x = 6

IT WILL TAKE HER 6 WEEKS.

Let's check and make sure we're correct:

Replace "x" as 6.

126 + 14(6) = 210

14 times 6 = 84

126 + 84 =210

Add them and 126+84 = 210

210=210

Therefore we know this answer is correct.

Thanks for your question.
