Respuesta :
1st year = 8000
2nd year = 8000 * 1.12 = 8960
3rd year = 8960*1.12 = 10035.20
4th year = 10035.20 * 1.12 = 11239.42
8000 + 8960 + 10035.20 + 11239.42 = 38234.62 round to $38,235
Answer:
$38,235 is needed.
Step-by-step explanation:
Given,
The cost of first year of college is $ 8000 and it is increasing by 12 % each year,
So, His first year's cost = $ 8000,
Second year's cost = 12 % more than the first year's cost = 112 % of first year's cost = 112 % of 8000 = 1.12 × 8000 = $ 8960,
Third year's cost = 112 % of second year's cost = 112 % of 8960 = 1.12 × 8960 = $ 10035.2
Fourth year's cost = 112% of third year's cost = 1.12 × 10035.2 = $ 11239.424
Hence, Total cost for four-year college education = 8000 + 8960 + 10035.2 + 11239.424 = $ 38234.624 ≈ $ 38235
⇒ $38,235 is needed.
