sweet-ann [11.9K]
First, subtract 700 from both sides and you are left with .15m≤50
Then divide both sides by .15 and you are left with m ≤ 333.33.  Thus, the limo can only travel 333.33 miles.

For the following exercises, solve each inequality and write the solution in interval notation.
Pie

Answer:

The solution of the given set in interval form is $(-\infty,-4] \cup[12, \infty)$.

Step-by-step explanation:

It is given in the question an inequality as $|x-4| \geq 8$.

It is required to determine the solution of the inequality.

To determine the solution of the inequality, solve the inequality $x-4 \geq 8$ and, $x-4 \leq-8$

Step 1 of 2

Solve the inequality $x-4 \geq 8$

$$\begin{aligned}&x-4 \geq 8 \\&x-4+4 \geq 8+4 \\&x \geq 12\end{aligned}$$

Solve the inequality $x-4 \leq-8$.

$$\begin{aligned}&x-4 \leq-8 \\&x-4+4 \leq-8+4 \\&x \leq-4\end{aligned}$$

Step 2 of 2

The common solution from the above two solutions is x less than -4 and $x \geq 12$.

The solution set in terms of interval is $(-\infty,-4] \cup[12, \infty)$.

2. A group of activists wants to raise money for a good cause, so they decide to sponsor a bicycle race. It receives $60 per cyc
Scorpion4ik [409]

Answer

Step-by-step explanation:

  • The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
  • Let x represent the number of cyclists.
  • Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:
  • Revenue = 60x + 15000
  • Also, the cost of the race is $18 per entry, hence:
  • Cost = 18x
  • They need to raise at least $57,000, hence:
  • Profit ≥ 57000
  • Revenue - Cost ≥ 57000
  • (60x + 15000) - 18x ≥ 57000
  • 42x ≥ 42000
  • x ≥ 1000
  • Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
