The <u><em>correct answer</em></u> is:
d) People per hour, because the dependent quantity is the people
Explanation:
In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.
The independent variable is the one that causes a change, while the dependent variable is the one that <em>gets</em> changed. In this situation, the number of people change every hour; this means the number of people <em>gets</em> changed, which makes it the dependent variable. This means that the independent variable must be time.
Since people is dependent and time is independent, "people per hour" would be the best form of this statement.
Answer:
x > 367
Step-by-step explanation:
set x = # of DVDs they sold
Each DVD costs $15 so the total amount they made is 15x
Since they raised more than $5500
15x > 5500
Divide both sides by 15 to solve the inequality and you get
x > 366.67 and since you can't sell 0.67 of a DVD, round up to get
x > 367 which means that they sold more than 367 DVDs
Answer:
"is" (and any subsequent words) was ignored because we limit queries to 32 words.
Let q = number of quarters.
Let p = number of pennies.
A quarter is worth $0.25. q quarters are worth 0.25q.
A penny is worth $0.01. p pennies are worth 0.01p.
All coins together are worth 0.25q + 0.01p.
We are told that all coins together are worth $8.58, so 0.25q + 0.01p must equal 8.58.
0.25q + 0.01p = 8.58
That is our first equation.
She has 8 times as many pennies as quarters, so
p = 8q
That is our second equation.
We have a system of equations.
0.25q + 0,.01p = 8.58
p = 8q
Since the second equation is already solved for p, we can use the substitution method.
We will substitute 8q for p in the first equation.
0.25q + 0.01p = 8.58
0.25q + 0.01(8q) = 8.58
0.25q + 0.08q = 8.58
0.33q = 8.58
q = 26
p = 8q = 8 * 26 = 208
She has 26 quarters and 208 pennies.
Check:
26 quarters are worth 26 * $0.25 = $6.50
208 pennies are worth $2.08
$6.58 + $2.08 = $8.58
The value of the coi8ns is correct.
Also, 208/26 = 8. The number of pennies is really 8 times the number of quarters.
Our solution is correct.
