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
