Hillary is planning an expensive surprise party. She is choosing between two venues. The banquet hall at Hotel A will cost $431
In-s [12.5K]

Answer: Hillary would have to invite 15 people before the cost of having the party at Hotel B is less than the cost of having a party at Hotel A

Step-by-step explanation:

Let x represent the number of guests that Hillary would invite.

The banquet hall at Hotel A will cost $431 to rent the room and $38 per guest. This means that the total cost of hosting x guests at hotel A is

38x + 431

The banquet hall at Hotel B will cost $747 to rent the room and $16 per guest. This means that the total cost of hosting x guests at hotel B is

16x + 747

For the cost of having the party at Hotel B to be less than the cost of having a party at Hotel A, it means that

16x + 747 < 38x + 431

747 - 431 < 38x - 16x

316 < 22x

22x > 316

x > 316/22

x > 14.36

Simplify (1/36)^n=216^n+5
Amanda [17]

Answer: - 2

Step-by-step explanation:

(1/36)^n = 216^n+5

(1/6^2)^n = (6^3)^n+5

(6^-2)^n = (6^3)^n+5

Opening the brackets

6^-2n = 6^3n+15

-2n = 3n + 15

collecting like terms

-2n - 3n = 15

-5n = 15

divide both sides by - 5

n = 15/-5

n = - 3

Dave also starts a new job, but his hourly pay starts at $7.25. Suppose that he gets a 40¢-per-hour raise each year.
pshichka [43]

Answer:

$8.5

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

<em>Dave also starts a new job, but his hourly pay starts at $7.25. Suppose that he gets a 40¢-per-hour raise each year. What will Vicky’s hourly pay be in 3 years</em>

My answer:

Given:

  • Rate per hour: $7.25.
  • Hour raise each year: 40¢-

=> the percentage of rate increasing:

(40¢ / $7.25)*100%

= (40¢ / 7.25*100¢)*100%

= 5.5%

What will Vicky’s hourly pay be in 3 years

This is a compound growth problem.  The formula is:

F=P(1+r)^t

<=> F = =7.25(1+0.055)^3

<=> F = $8.5

So the rate after three years is $8.5

Hope it will find you well.
