A student is pricing two different picture packages.

Question

John’s Photo World charges a one time sitting fee of $125 and $2 for each photograph ordered. Sam’s Picture Emporium charges a one time sitting fee of $140 and $1.50 for each photograph ordered. For how many photographs ordered will the companies charge the same amount?

Answer 1

125 + 2N = 140 + 1.50N

 

2N + 125 - 1.50N - 140 = 0 <--- everybody on the left side

 

0.50N - 15 = 0

 

0.5N = 15

 

N = 30

 

 

Answer 2

p represents the number of photos

125 + 2p = 140 + 1.50p

 

Can you solve for p and answer?
