Answer:
Statement A is true.
Step-by-step explanation:
A. If the group sells 15 prints, they will lose $85.
B. If the group sells 12 prints, they will lose $204.
C. If the group sells 35 prints, they will make $935.
D. If the group sells 28 prints, they will lose $136.
f(p) = 17p - 340
p = prints
f(p) = profit
Let's check the statements to see which one is true.
A. 17.15 - 340 = - 85 OK!
B. 17.12 - 340 = -136 (false, they will lose $136)
C. 17.35 - 340 = 255 (false, they will make $255)
D. 17.28 - 340 = 136 (false, they will make $136)

Answer:
5:6
20:24
30:36
Step-by-step explanation:
In order to find an equivalent ratio, you have to multiply or divide your numerator and denominator by the same number.
For example:
10/12 x 3/3
30/36 = 30:36
10/12 is equivalent to 30:36
Answer:
24 mph for both 60 miles and 40 miles.
Step-by-step explanation:
We need to find how long it takes to get to college and from it.
Speed x time (x) = Distance (60)
30x = 60
x=2
It takes two hours to get to college
20x = 60
x = 3
It takes 3 hours to get back. It's a total of 5 hours, 2 hours at 30mph and 3 at 20. Now we need to find the average
30+30+20+20+20=120
120/5= 24
The average speed for the round trip is 24.
To do the second part, we follow the same process, but replace 60 with 40 for distance.
30x=40
x= 1.33
20x=40
x=2
We can add the total distance and divide by total time to find the average.
The total distance is 80. Time is 3.33
80/3.33=24
The average speed is still 24.
