Answer:

$2.44745763 \times {10}^{6}$

Step-by-step explanation:

$R = \frac{ {x}^{2} }{y} \\ \\ = \frac{ {(3.8 \times {10}^{5}) }^{2} }{5.9 \times {10}^{4} } \\ \\ = \frac{14.44 \times {10}^{10} }{5.9 \times {10}^{4} } \\ \\ = 2.44745763 \times {10}^{10 - 4} \\ = 2.44745763 \times {10}^{6}$

<u><em>function </em></u>: p(x) = 65 + 25(x)

for 3 sells

p(3) = 65 + 25(3)

p(3) = 140

for 10 sells

p(10) = 65 + 25(10)

p(10) = 315

So,

140 ≤ p(x) ≤ 315
