Answer:
He will have 6,408 dollars in the next 3 years.
Step-by-step explanation:
They are not in proportion, since its 6:9 round it down (2:3) so pretend the 6 are apples and the 9 are oranges
Every 2 apples there are 3 oranges
So having 9 apples what is that?
2 x ? = 9
2 x 4.5 = 9
So if you want to keep 2:3 you have you times the oranges by 4.5 aswell!
3 x 4.5 = 13.5
So since it is 9:12 not 9:13.5 they are not in proportion
Plan 1 costs $34.99 per month.
For 12 months, it would cost 12 * $34.99 = $419.88
Plan 2 cost $134.97 for 3 months.
A year is 12 months, so it has 4 periods of 3 months.
In one year, this plan would cost 4 * $134.97 = $539.88
She should choose Plan 1.
She will save $539.88 - $419.88 = $120
