1 answer:
Answer:
c. 19
Step-by-step explanation:
You must find everyone's age.
Toni is 21 and Toni's age plus Maria's age is 36. so 36-21= 15.
This tells us that Maria is 15.
Jacob's age plus Maria's age is 29. to find Jacobs age we need to subtract Maria's age from 29, 29-15 is 14.
Maria is 15,
Jacob is 14,
and Toni is 21.
Jacobs age plus marcels age is 33, so now we need to subtract Jacobs age to 33. 33-14 = 19
Marcel is 19 years old.
I hope this wasn't confusing and it helped. Have a good day.
