Answer:
The equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.
Step-by-step explanation:
Since the initial starting salary for a summer camp counselor is $ 14 per week, and starting with the first week, the salary doubles to encourage the counselor to work for the entire summer, to write an equation that models the salary (y) of the camp counselor per week (x), and determine, if the camp runs for 12 weeks, how much would a camp counselor make, the following calculations should be performed:
14x2 ^ X = Y
14x2 ^ 12 = Y
14x4,096 = Y
57344 = Y
Therefore, the equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.
Answer:18
Step-by-step explanation: She gave 3 children 3 pieces each. 3*3=9. She also took 9 pieces for herself. 9+9=18
Short Answer: 18 minutes
Remark
The answer to this problem is less than the smallest time of the two people working together. that fact lets out C and D (38 minutes and 75 minutes). Now you have to choose 15 minutes and 18 minutes. There's a method. No guessing needed.

Let the time for Sophie = S
Let the time for Simon = M
Let the job to completion = 1
S = 45 minutes
M = 30 minutes
Step One
Convert minutes to hours.
45 minutes = 45 / 60 = 3/4 hour = 0.75 hour
30 minutes = 30 / 60 = 1/2 hour = 0.50 hour
Step Two
Set up the Equation
The formula is a form of job / hour.
Let the time = t that they both have to work
job = 1 in these problems.
1/S + 1/M = 1/t
1/0.75 + 1/0.5 = 1/t
Solve
1 ÷ 0.75 = 1.33333
1 ÷ 0.5 = 2
1.3333 + 2 = 3.33333
3.3333 = 1 / t Multlply both sides by t
3.3333*t = 1
t = 1 / 3.333333333
t = 0.3 of an hour
1 hour = 60 minutes
0.3 hours = x Cross Multiply
x = 60 * 0.3
x = 18 minutes
Answer working together it took them 18 minutes <<<<<
