Question

Jenna and her friend, Khalil, are having a contest to see who can save the most money. Jenna

has already saved $110 and every week she saves an additional $20. Khalil has already saved $80
and every week he saves an additional $25. Let x represent the number of weeks and y represent
the total amount of money saved.

So far I've got 110+20x= ??? for jenna because I don't know what goes after the equal sign and 80+25x=???

Answer 1

Put them equal to each other and you'll find how many days it takes Khalil to catch up. additional days he'll be ahead before them he's behind.
