Question

Jessica and her 2 sisters want to take a camping trip. They have $225 saved. Each of them will save $21 a week until they have at least $512 to pay for the trip. How much money will they save after 4 weeks? Will they have enough money to pay for the trip?

Answer 1

Answer:

$477 ; No

Step-by-step explanation:

In this example, there are three people involved: Jessica and her two sisters. If Jessica and her two sisters are each able to save $21 a week, this means that they are able to save $63 a week in total:

3* 21 = 63

As they have four weeks, they will be able to make $252 in total:

63 * 4 = 252

This would be added to the amount that they have already saved, which is $225:

252 + 225 = 477

This means that they will not have enough money after 4 weeks.

Answer 2

Answer:

$561, yes!

Step-by-step explanation:

after 4 weeks, they will have 21*4=$84 per kid (4 kids). Therefore we need to multiply this by 4. 84*4=$336. You must remeber that they started with $225, so 225+336=$561, which is more than $512, so they can pay for the trip!
