Final answer:
To calculate the amount of money you will need to save for the next 3 years, subtract your scholarship amount from the total cost and calculate 30% of the remaining cost, then multiply this amount by 3.
Step-by-step explanation:
To calculate the amount of money you will need to save for the next 3 years, we'll first determine the remaining cost after the scholarship amount. The remaining cost is obtained by subtracting the scholarship of $2,000 from the total cost of $8,000, resulting in $6,000. Next, we'll calculate 30% of this remaining cost by multiplying it by 0.3, which gives us $1,800. Since this $1,800 is the amount your family will pay, you will need to save the difference between this amount and the remaining cost for each year, which is $6,000 - $1,800 = $4,200 per year.
To calculate the total amount of money you will need to save for the next 3 years, we'll multiply the amount you need to save per year ($4,200) by the number of years (3). So, you will need to save a total of $4,200 x 3 = $12,600 for the next 3 years.
