Can someone give me the answer to this and explain : /

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=
