Answer:
Crew: 32
Marty: 48
Blakely: 24
Step-by-step explanation:
I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.
32 × 1. 5 = 48
Marty is 48. Now, let's find Blakely's age.
32 × 0.75 = 24
Add all the ages together.
32 + 48 + 24 = 104
Hope that helps.
Crew's age is 32, Marty's age is 48 and Blakey's age is 24
Let :
c represent Crew's age
m represent Marty's age
b represent Blakely's age
From the question, the following can be derived
m = 1.5c
b = 0.75c
m + b + c = 104
Substitute for m and b in the above equation
c + 1.5c + 0.75c = 104
3.25c = 104
divide both sides of the above equation by 3.25
c = 104 / 3.25
c = 32
Substitute for c in the equations that represent Marty and Blakely's age
m = 1.5c
m = 1.5(32)
m = 48
b = 0.75c
0.75(32)
b = 24
