Question

The equation, c = 15p+ 40 shows how the number of guests p Jackie wants to have a party and the total cost, c are related. Jackie had (?) a guest at her party because she spent $1,165.

A.25
B.50
C.75
D.250

Answer 1

Using the equation c = 15p + 40, by plugging in the total cost of $1,165 and solving for p, we find that Jackie had 75 guests at her party.

Step-by-step explanation:

The equation c = 15p + 40 represents the total cost, c, of having a party with a certain number of guests, p. To calculate the number of guests Jackie had at her party, we substitute the given cost of $1,165 into the equation and solve for p:

1165 = 15p + 40

Subtract 40 from both sides:

1125 = 15p

Divide both sides by 15:

p = 1125 / 15

p = 75

Therefore, the correct answer is C.75, meaning Jackie had 75 guests at her party.
