Question 271086: how can I make a table to show this problem? Lisa is 15 years old. Mark is 49 years old. How old will they both be when Mark is 3 times older than Lisa Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let x be the years from now when their ages have a 3:1 ratio.
(49+x)/(15+x) = 3
49+x=3(15+x)
49+x=45+3x
2x=4
x=2
.
49+2=51
15+2=17
