Deena works add a customer service call center. she fields an average of five calls per hour. employees are encouraged to field more than 200 calls per week. deena has already fielded 85 calls this week. how many hours, x, does deena need to work this week to reach the weekly goal of fielded calls if she continues to field and average of five calls per hour? select the any quality that includes the fewest number of hours deena can work on this week and still reach the weekly goal.
a. x > 28
b. x > 40
c. x > 2
d. x> 23

D. x>23

Step-by-step explanation:

Deena's goal is to take 200 calls this week.

She already answered 85 calls this week, so she's missing 115 (200-85) calls for her goal.

She takes about 5 calls per hour, so how many hours does she need to work more?

h = 115 calls / (5 calls/h) = 23 hours

So, she needs to work at least 23 more hours... so x > 23.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
