Mr. Nielsen invested $250,000 in two different automobile companies. The first earned a 5% profit, and the second earned a 10% p
dem82 [27]

Answer: $100,000


Step-by-step explanation:

Let P be the amount he invested in 5% profit .

then 250,000-P be the amount he invested in 10% profit .

The total profit he earns at 5% =5% of P

⇒The total profit he earns at 5 %=0.05P

Now, The total profit he earns at 10% =10% of (250,000-P)

⇒The total profit he earns at 10%=0.1(250,000-P)=25,000-0.1P

According to the question,

3(0.05P)=25,000-0.1P\\\Rightarrow\ 0.15P=25,000-0.1P\\\Rightarrow\ 0.25P=25,000\\\Rightarrow\ P=\frac{25000}{0.25}\\\Rightarrow\ P=100,000

Thus, the money he invest in the company that made 5%= $100,000

Use the symbolic form of the gas cost of fill-up function,, to evaluate
UkoKoshka [18]

Answer:

0, $12.40, $24.79, $37.19, $49.58

0 ≤ f(g) ≤ 49.58

Step-by-step explanation:

The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)

So, f(0) = $0

f(5) = 2.479 × 5 = $12.40

f(10) = 2.479 × 10 = $24.79

f(15) = 2.479 × 15 = $37.19

and f(20) = 2.479 × 20 = $49.58

And the practical range of this function is 0 ≤ f(g) ≤ 49.58

Therefore, option D is correct. (Answer)
