Answer:
The discount was A) $ 24.51 and B) 14.5% of the value.
Step-by-step explanation:
Since a department store offered a 10% discount on all humidifiers, and they also stated that the first 50 customers would receive an additional 5% discount off the sale price, if I purchase a humidifier that sells for $ 169 and I are among the first 50 customers, to determine what will my total discount be (a) in dollar amount and (b) in percent, the following calculation must be performed:
100 - 10 = 90
100 - 5 = 95
(169 x 0.9) x 0.95 = X
152.1 x 0.95 = X
144.49 = X
169 = 100
144.49 = X
144.49 x 100/169 = X
85.5 = X
Therefore, the discount was A) $ 24.51 and B) 14.5% of the value.

Answer:
- Infinitely many solutions
Step-by-step explanation:
- 2x + x + 4 = 3x + 4
- 3x + 4 = 3x + 4
Both sides of the equation are exactly same.
It means regardless the value of x the equation is true.
The equation has infinitely many solutions.
Compare the linear function given with the slope-intercept form of a line, given by,
Where m is the slope and b is the y-intercept.
Comparing tells us that 10 is the slope. What does it mean?
<em>It means for </em><em>every unit increase in w (weeks)</em><em>, there is a </em><em>10 unit increase in number of laps</em><em>. </em>
This is choice 4.
ANSWER: "The number of laps Jessica increased her swim by each week"
