Answer:
If this is your question -
Jennifer is saving money to buy a bike. The bike cost $252. She has $199 saved, each week she adds $19 to her savings. How long will it take her to save enough money to buy the bike?
The answer will be 7 weeks.
Explanation:
You first of all take the $252 and subtract it by $199.
Why? Because $199 is the amount of money she currently has in her savings for her bike, and $252 is the cost of the bike. By subtracting them, she'll figure out the amount of money she still needs.
252 - 199 = 133
That means, she still needs $133.
We also know that she adds $19 to her savings each week.
So what we can do is multiply 19 by a number and see what equals 133.
19 × 6 = 114 (not working)
19 × 7 = 133
19 × 8 = 152 (not working)
Now we found out that 19 × 7 = 133.
Remember, 133 is amount she still needs.
What each number means -
19 is the amount of money she adds per week.
7 is the amount of weeks she'll take to reach her goal
133 is the amount of money she needs until she can buy her bike
So, in conclusion, in 7 weeks, she'll have enough money to buy her bike.
I don't know if it was clear enough's but I hope it helps!
