Answer:
67.3684% or 67%
Step-by-step explanation:
percent increase = 100 X (final amount-initial amount)/(initial amount)
so
percent increase = 100 X (159-95)/95
159 - 95 = 64
64/95 = 0.6736842105263158
0.6736842105263158 X 100 = 67.36842105263158

Answer:
$6062
Step-by-step explanation:
The formula we are given is
![c=120\sqrt[3]{n^2}+1300](https://tex.z-dn.net/?f=c%3D120%5Csqrt%5B3%5D%7Bn%5E2%7D%2B1300)
We will replace n with 250:
![c=120\sqrt[3]{250^2}+1300\\ \\=120\sqrt[3]{62500} +1300\\\\=120(39.685)+1300\\\\=4762.20+1300\\\\=6062.20 \approx 6062](https://tex.z-dn.net/?f=c%3D120%5Csqrt%5B3%5D%7B250%5E2%7D%2B1300%5C%5C%20%5C%5C%3D120%5Csqrt%5B3%5D%7B62500%7D%20%2B1300%5C%5C%5C%5C%3D120%2839.685%29%2B1300%5C%5C%5C%5C%3D4762.20%2B1300%5C%5C%5C%5C%3D6062.20%20%5Capprox%206062)
the answer is 15 because 12 is 80% of 15
