You can put this solution on YOUR website!
let n = number of newspapers
;
"diane delivers newspapers for $5 a day plus $0.04 per newspaper delivered."
f(n) = .04n + 5
:
" jeremy delivers newspapers for $2 a day plus $0.10 per newspaper delivered."
f(n) = .10n + 2
:
"how many newspapers would diane and jeremy each need to deliver in order to earn the same amount?"
.10n + 2 = .04n + 5
.10n - .04n = 5 - 2
.06n = 3
n = 3/.06
n = 50 newspapers for them to both earn $7
