Answer: a. p = c/5 - 43        b. 17 people

Step-by-step explanation:

c= 5p + 215  

A)  a said solve for p so we will solve for p in the equation.

c= 5p + 215  First   Subtract 215 from both sides

-215     -215  

c - 215 = 5p Now divide both sides by 5.

p = c/5 - 43  

B)  If c is the total cost  of hosting a birthday party then we will input 300 into the equation for c and solve for p.

300 = 5p + 215    First subtract 215 from both sides

-215             -215

 85 = 5p      Divide both sides by 5

 p = 17  

This means  17 people can attend the meeting if Allies parents are willing to spend $300.

The number of people that can attend the party will be 17

Since the formula given is represented by c = 5p + 215, to solve for p, we've to use subject of the formula and this will be:

c = 5p + 215

c - 215 = 5p

p = (c - 215)/5

p = c/5 - 43

Based on the equation given, the number of people that can attend the party will be:

c = 5p + 215

300 = 5p + 215

Collect like terms

5p = 300 - 215

5p = 85

p = 85/5

p = 17

Therefore, 17 people can attend the party.
