Answer:
m= 120 - 6*d
Step-by-step explanation:
budget is $120 per 1 month, spends $6 per 1 day
on the the table you have 2 columns: one labele it "days" and one "$ spent" and fill it in:
days: 1,2,3,4,..
$ spent: 6, 6*2=12, 6*3= 18, 6*4= 32,...
on the graph lable the horizontal axis "days" and the vertical axis "$ spent"
now plot the points (1,6), (2,12),(3,18), ..., and draw a line trough them
the equation is
m= 120 - 6*d
so after 20 days for example, out of 120 will have m=120-6*20=120-120=0,
$0 wil have in 20 days
