Answer:
Save $483.34 per month for the next 5 years.
Explanation:
Tuition Cost per year of college = $14,000
Total tuition cost for 4 years of college:
[tex]\begin{gathered} =14,000\times4 \\ =\$56,000 \end{gathered}[/tex]• Becky has already saved $10,000
,• Her grandparents promised to contribute $4,250 for 4 years.
,• Her parents will save $x for 5 years (60 months).
Therefore:
[tex]10,000+4(4250)+60x=56,000[/tex]We solve for x:
[tex]\begin{gathered} 10,000+17,000+60x=56,000 \\ 27,000+60x=56,000 \\ 60x=56,000-27,000 \\ 60x=29,000 \\ x=\frac{29,000}{60} \\ x=\$483.33 \end{gathered}[/tex]Therefore, her parents must save $483.33 per month for the next 5 years.
