Jace's average gross pay is $1,630.00 bi-weekly. Determine how many years it will take Jace to earn his first million dollars.
vesna_86 [32]

The number of years it will take to earn his first million is 24 years

Average bi-weekly gross pay = $1,630

Bi-weekly = 2 weeks

Number of 2 weeks(bi-weeks) in a year = 26 bi-weeks

The least million he can earn is $1,000,000

Let the number of years = n

We could use the equation :

Least million = gross pay × (Number of bi-weeks × number of years)

1000000 = 1630 × (26n)

1000000 = 42380

Divide both sides by 34230

1000000 / 42380 = n

n = 23.59

The least number of years is 24.

A magnet school program was set up to bring in students from all over the city. With the first 112 students, the magnet program
Galina-37 [17]

Answer

Find out the percentage of students from the north side of the city in the program .

To prove

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

A magnet school program was set up to bring in students from all over the city. With the first 112 students .

the magnet program had 50% from the south side of town, 12.5% from the north side l, and 37.5% from the east side.

12 .5 % is written in the decimal form.

= \frac{12.5}{100}

= 0.125

North side student be = 0.125 × 112

                                     = 14

As given

If 6 more student from the north side and 2 students from the west side side enrolled in the program .

than north side student becomes = 14 + 6

                                                        = 20

Total number of student becomes = 112 + 6 + 2

                                                         = 120

put in the above formula

Percentage =\frac{20\times100}{120}

Percentage =\frac{2000}{120}

                          = 16.66% (approx)

Therefore  16.66% (approx) students from the north side of the city in the program .
