Answer:
Sandy will receive $800
Steve will receive $600
Step-by-step explanation:
Sandy : Steve = 4 : 3
Sandy = 4
Steve = 3
Total ratio = 4 + 3 = 7
Total prize money = $1400
How much does Sandy receive ?
Sandy's share = Sandy's ratio / total ratio × Total prize money
= 4 / 7 × 1400
= 4 × 200
= $800
Sandy will receive $800 out of $1400
Steve's share = Steve's ratio / total ratio × Total prize money
= 3 / 7 × $1400
= 3 × $200
= $600
Steve will receive $600 out of $1400
Check:
Sandy's share + Steve's share
= $800 + $600
= $1400

Answer:
<h2> $9</h2>
Step-by-step explanation:
<h2>
f(x) = - 25 ( x - 9 )² + 200</h2>
<em>when</em><em> </em>x = 5 ,
f(5) = - 25 ( 5 - 9 )² + 200 = - 200
<em>when</em><em> </em>x = 9 ,
f(9) = - 25 ( 9 - 9 )² + 200 = 200
<em>when </em>x = 10 ,
f(10) = - 25 ( 10 - 9 )² + 200 = 175
<em>when</em><em> </em>x = 15 ,
f(15) = - 25 ( 15 - 9 )² + 200 = -700
∴ when <u>price = $9</u>
the company receive the maximum profit
