Question

Jason and his 3 brothers want to buy a gift fr their mother. they have $314 saved. each of them will save $17 a week until they have at least $515 for her gift. how much money will they save after 3 weeks? will they have enough money to buy the gift?

Answer 1

With each of them saving $17 a week for 3 weeks, they will be able to save up $153 after three weeks. Adding this amount to the original amount they had will give them $467. Obviously, they will not have enough money to buy the gift they want for their mother. They will be short of $48. 

Answer 2

Answer:

After 3 weeks they will have saved $204. They will have enough money to buy the gift ($518).

Step-by-step explanation:

We have the following data to solve this problem :

Jason and his 3 brothers want to buy a gift for their mother (There are 4 people saving for the gift).

They have $314 saved.

Each of them will save $17 a week

They need at least $515 for the gift.

We want to know the amount of money saved after 3 weeks. To calculate this we need to multiply the number of weeks per the amount of money each person can save every week and per the number of people ⇒

$(3Weeks).(17\frac{Dollars.Person}{Week}).(4people)=204$

We find out that after 3 weeks Jason and his brothers will save $204.

If we want to know if the amount of money is enough for the gift we need to sum this value to the previous saved money.

$314 + $204 = $518

Therefore after 3 weeks Jason and his brothers will have $518 for the gift.

$518 > $515 ⇒ They will have enough money to buy the gift.
