Answer:
After 3 bracelets , the money taken in and the number of bracelets sold will be the same for the girls
Step-by-step explanation:
Let the number of bracelets that makes the amount of profit made be equal be x
For Sandy, her gain will be 10x - 25
For Selena, her gain will be 26x - 73
So equating both, we can find x
10x - 25 = 26x - 73
26x-10x = 73-25
16x = 48
x = 48/16
x = 3
To get the amount, we can make a substitution for x
we have;
10(3) - 25 = 30-25 = $5
Answer: 3,000
Step-by-step explanation:
Divide 48,000 by 16
48,000 ÷ 16 = 3,000

Answer:
In 14 weeks will they have the same number of good behavior stars
Step-by-step explanation:
Let
x ----> the number of weeks
y ----> the number of good behavior stars
we know that
<em>Alice</em>
----> equation A
<em>Mack</em>
----> equation B
To find out in how many weeks will they have the same number of good behavior stars, equate equation A and equation B
Solve for x
<u><em>Verify</em></u>
For x=6 weeks
<em>Alice</em>
<em>Mack</em>
therefore
In 14 weeks will they have the same number of good behavior stars
