Sagot :

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.
