If twice the son's age in years is added to the father's age, the sum is 70. But twice the father's age is added to the son's age, the sum is 95, find the present ages of the father and his son.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
