Question

JA TONTTI
Jack said, “Five times my age in 2 years is 100."
How old is Jack now?

Answer 1

19 years, 7 months, and six days old

Explanation:

100-2=98/5=19.6

Answer 2

18 years old

Explanation:

Break it down: 5×(age in 2 yrs)=100

Rewrite with a variable: 5×(x+2)=100

Multiply it out: 5x + 10 = 100

Isolate the x term: 5x = 90

Isolate the x: x = 18
