D) is correct.
Looking at the graph, it goes through the point (2, 200) and is very near the point (3, 300). This means it increases by nearly 100 every month; this tells us how much she saves each month.
Answer:
Step-by-step explanation:
when 13 bought we find these inequalities
x + 12y < 7 no
2x + 11y < 7.5 no
3x + 10y < 8 no
4x + 9y < 8.5 no
5x + 8y > 9 yes
When 14 bought we find these inequalities
x + 13y < 7.5 no
2x + 12y < 8 no
3x + 11y < 8.5 no
4x + 10y > 9 yes
Tripiling time is
t=time elapsed
r=tripling time
P=initial amount
so
when time is measured in minutes
if measured in hours then
or
