Answer:
Jarrett has 75 comics
Step-by-step explanation:
T = Number of comic books Toby has.
M = Number of comic books Mitch has.
J = Number of comic books Jarrett has.
Toby has 75% as many comic books as Mitch.
T = 3/4 * M
This is because 75% = 75/100 = 3/4
Jarrett has 25% more comic books than Mitch.
J = 5/4 * M
This is because 125% = 125/100 = 5/4
If Toby has 45 comic books, how many comic books does Jarrett have.
1) Substitute T = 45 and Solve for M
T = 3/4 * M
45 = 3/4 * M
45 ÷ 3/4 = M
45 * 4/3 = M
180/3 = M
M = 60
2) Substitute M = 60 and Solve for J
J = 5/4 * M
J = 5/4 * 60
J = 300/4
J = 75

The total weight of candies is unknown. Let x = the total weight of candies.
"One student ate 3/20 of all candies and another 1.2 lb":
The first student ate (3/20)x plus 1.2 lb which is 0.15x + 1.2.
"The second student ate 3/5 of the candies and the remaining 0.3 lb."
The second student ate (3/5)x and 0.3 lb which is 0.6x + 0.3.
Altogether the 2 students ate 0.15x + 1.2 + 0.6x + 0.3.
That was all the amount of candies, so that sum equals x.
0.15x + 1.2 + 0.6x + 0.3 = x
Now we solve the equation for x to find what the total amount of candies was.
0.75x + 1.5 = x
-0.25x = -1.5
x = 6
The total amount of candies was 6 lb.
The first student ate 0.15x + 1.2 = 0.15(6) + 1.2 = 0.9 + 1.2 = 2.1, or 2.1 lb of candies.
The second student ate 0.6x + 0.3 = 0.6(6) + 0.3 = 3.6 + 0.3 = 3.9, or 3.9 lb of candies.
Answer: The first student ate 2.1 lb of candies, and the second student ate 3.9 lb of candies.
