Question

4. Kristin is 2 years older than Susan, and Kate's age is 3 years less than twice Kristin's age.

How old is Kristin if the sum of all three of their ages is 47 years?
f. 11
g. 13
h. 23
j. 24
k. 36

Answer 1

Kristin is 13 !! , i took 13 for Kristins age, and took 13-2 for Susans age which leaves 11, 13+11 = 24. i multiplied 13 twice and got 26 and subtracted 3 for Kates age, and got 23. 24+23 = 47.
