Based on Janice average, she spent $50 at the last store.
Let a, b, c, d, e represent the money spent on the five stores respectively.
Since she spent an average of $30 at each store, hence:
(a + b + c + d + e) / 5 = 30
(a + b + c + d + e) = 150
She spent $100 on the first four stores, hence:
a + b + c + d = 100
(a + b + c + d + e) = 150
100 + e = 150
e = 50
Hence based on Janice average, she spent $50 at the last store.

Please i need this now
Answer:
356
Step-by-step explanation:
She will earn a total of $296.
We have - Alani who has a summer job as a lifeguard. She makes $8/h for up to 40 h each week. If she works more than 40 h, she makes 1.5 times her hourly pay, or $12/h for each hour over 40 h. How much will Alani earn if she works: a. 37 hours.
We have to determine - How much will Alani earn if she works for 37 hours.
If you earn $x per hour and you work for 30 hours, them calculate the amount of money you will earn.The amount of money you will earn will be = $30[tex]x[/tex].
According to question, we have -
Pay per hour = $8
Number of hours she work in a week = 40 hours
For working 37 hours, which is less than 40, she will receive an hourly wage of $8 only. Therefore -
$8 x 37 = $296
Hence, she will earn a total of $296.

Step-by-step explanation:
I’m assuming this a z-score for stats. You would just go into your calculator, in my case a Casio. Then, you’d press on the stats module, click F5 (DIST), F1 (NORM), F3 (InvN). You would change the data to variable, then put in tail right, area .9207, SD 1, mean of 0. Then hit execute and you’ll get the answer of -1.4097958. Round it if needed.

Find the greatest common factor of 50,75, and 150
Answer: 25
Step-by-step explanation:
To find the greatest common factor of an number, you start by listing the factors of each number. The factor that appears the greatest amount of times is the greatest common factor.
175: 1,5,7,25,35,175.
75: 1,3,5,15,25,75.
25:1,5,25.
The number 25 in this case appears the most frequently, therefore the answer is 25.
The greatest common factor (GCF), of the given numbers 50, 75, and 150 is 25.
To find the GCF, we identify the common factors of the given numbers and then select the largest one. The common factors of 50, 75, and 150 are the numbers that divide each of them without leaving a remainder.
In this case, 25 is the largest number that divides all three numbers evenly.
50 = 2 × 5 × 5
75 = 3 × 5 × 5
150 = 2 × 3 × 5 × 5
Since 25 is present as a factor in all three numbers, it's the greatest common factor.
Therefore, The GCF of 50, 75, and 150 is 25.

C. 21
B. 19
A. 20
The amount that will be gotten by each nephew when Virgie will equally give P 742.60 among her 4 nephews will be $185.65.
Since Virgie will equally give P 742.60 among her 4 nephews, the amount that each nephew gets will be:
= 742.60 / 4
= $185.65
If Php 5876 are distributed equally among 26 men, the amount that each person gets will be:
= Php 5876 / 26
= Php 226
If Bernard wants to cut a straight board into 4 equal pieces and the board is 112.12 cm, the length of each piece will be:
= 112.12cm / 4
= 28.03cm
The number of 25cents coins that are equal to P 5.00 will be:
= 5/0.25
= 20
There will be 20 25 cents coins on P5.00.
