Answer:

Jan 2018: 7.83 million
Feb 2017: 8.12 million

Step-by-step explanation:

Your "Grandma formula" tells you ...

N = G(1 +x/100)

Solving for G gives ...

G = N/(1 +x/100) . . . . . . G = old value; N = new value; x = % change

For this problem, N=7.9 million.

1) x = 0.9, so G = 7.9/(1 +.9/100) ≈ 7.83 . . . million

7.83 million people were looking for work in January 2018.

2) x = -2.7, so G = 7.9/(1 -2.7/100) ≈ 8.12 . . . million

8.12 million people were looking for work in February 2017.

VERY EASY WILL GIVE BRAINLEST THANK YOU AND FRIEND YOU Determine whenter (18+35)x4= 18+35x4 is true or false. Explain.

Ray Of Light [21]

Answer:

False because on the left side of the equation you are adding 18 and 35 first and on the right you are multiplying 35 and 4 first. This will give you an unequal equation when solved.

Let's solve each side

(18+35)*4=212

You have worked as a guide at the aquarium for two summers. This summer you have been offered the job again, but with a 4 percen

olga nikolaevna [1]

Answer:

More earn this summer per month = $30 more

Entire summer earning (for 2.5 months) = $1950

Step-by-step explanation:

For 2.5 months, you got 1875 dollars, so per month salary is:

1875/2.5 = $750 per month

This summer, you got a 4% raise, that means:

4% = 4/100 = 0.04

The raise is:

0.04 * 750 = $30 raise

So, new monthly salary is:

750 + 30 = $780

So, assuming you will work 2.5 months again this summer, you total earnings would be:

2.5 * 780 = $1950
