During Rachel’s birthday party, Rachel thinks about the ages of her parents and herself. Rachel says, “Hey, Mom and Dad, together your ages add up to 100 years!” Her dad is surprised. “You are right,” he says, and your age and mine total 64 years.” Rachel replies, “And my age and Mom’s total 58.” how old is rachel?

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
