4. If you are saving $ 5 dollars a week, in how many weeks you will be able to save $3000?

Can you write an equation to solve it? let w be the number of weeks) in how many years you

will be able to save $3000? (can you write an equation to solve it? let n be the number of

years.

11 yrs and 28 weaks

Step-by-step explanation:

1. Let w=week; n=Yrs

As we know that n = 52*w

2. let S1 be the saving of 1 week and S2 will be saving of yr. so

S2 = 52xS1

S2 = 260 $ = n

if S3 is Total Savings then

3. S3 = 260 x 10 + 400

S3 = 10 x S2 + 1 x S2 + 140

S3 = 11 x (n) + 28 x (w)

where n = 260 $; w = 5 $

4. So 11 yrs and 28 weeks will take to save 3000 $

3000/5=600

Answer:600
