Brandon estimates that he will need $18,000 each year to attend a 4-year college. His family can pay $5,000 a year. And he can get a student loan for $10,000 each year. If he saves $250 a month, how many months will it take him to save the rest of the money he will need for college?

It will take him 48 months.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

the amount his family can pay per year (5000) multiplied by 4 (since is a 4 year college) ; plus the amount of the loan he gets per year (1000) also multiplied by 4 ; plus the amount he saves per month (250) multiplied by the number of months (m) must be equal to the amount he will need per year for college (18000) multiplied by 4.

Mathematically speaking

18000 x 4 = (5000 x 4) + (10000x 4) + 250 m

Solving for m

72000= 20,000+ 40,000+ 250m

72,000-20,000-40,000 = 250m

12,000= 250m

12,000/250 = m

48 =m

its 4 because 2 times 2 is 4, if you double the number two you get four
