Answer:

a) 300 + 80h = x

b) $780

Step-by-step explanation:

So, the original cost is $300, plus an additional $80 times the number of hours rented.

h will represent the number of hours rented

x will represent our total cost (use whatever variable your teacher expects :))

300 + 80h = x

This is our equation. Now, we want to find the cost for 6 hours. Substitute 6 in for h.

300 + 80(6) = x        Solve for x.

 300 + 480 = x

            780 = x        This means the total cost for 6 hours will be $780.

Hope this helps :)

NOTE: I noticed in part a, it referred to a "dunking booth". I solved this problem as if that was a typo and they were referring to the jumper.

ziro4ka [17]

Answer:

Step-by-step explanation:

Interest earned during the rest of 2 years and 6 months

40 + 40 + 40 = 120

he will be getting 1000 at the time of maturity ie after 2.5 years .

Total receipt = 1000 + 120 = 1120

investment made = 820

total receipt earned = 1120

profit made = 300

time = 2.5 years

profit = investment x rate of intt x time / 100

300 = 820 x r x 2.5 / 100  where r is rate of interest

r = 30000 / 820 x 2.5

= 14.63 % .

Simplify 5sqrt 12xm^3 <br> Assume x and m are nonnegative
fredd [130]

Answer:

The right answer to your question is the third option

Step-by-step explanation:

            5 √12xm³

             First find the prime factors of 12

   12   2

     6   2

    3    3

     1             Then 12 = 2² 3

   and m³ = m m²

So    5 √ 2² 3 x m m²

and   5 (2)(m) √ 3xm

         10 m √ 3xm

Answer:

  $3

Step-by-step explanation:

The cost that hasn't been covered by bake sale proceeds is ...

  $750 -150 = $600

If that cost is divided among 200 students, the amount each student needs to pay is ...

  $600/(200 students) = $3/student

They need to charge $3 per ticket.
