Mashutka [201]

Answer: Yes, He will.

Step-by-step explanation:

Here, the amount he puts in each week = $ 59

In one year the number of weeks = 26

Thus, the total amount he can save in one year = 59\times 26 = 1534

According to the question,

His total saving in one year ≥ 1500

Since,    1534 > 1500

Thus, he will reach his goal.

The population of the town increased from 175000 to 262500 in a decade. What is the average percent increase of population per y
Alenkinab [10]

Answer:

5%

Step-by-step explanation:

As given,

The population of the town increased from 175000 to 262500 in a decade.

⇒ In 10 years , population increased from 175000 to 262500

⇒% increase = \frac{262500 - 175000}{175000}× 100% = \frac{87500}{175000}×100% = 0.5×100% = 50%

Now,

Average % increase = \frac{percent increase}{Total years} = \frac{50}{10}% = 5%

∴ we get

Average percent increase of population per year = 5%
