A photo studio offers portraits in 8x10 and wallet-sized formats. One customer bought two 8x10 portraits and four wallet-sized portraits and paid $52. Another customer bought three 8x10 portraits and two wallet sized portraits and paid $50. What is the cost of a wallet-sized portrait?
I have to write a system of equations for this.
I did: 52= 2x+4y
50= 3x+2y
I'm not sure if this system is correct so will somebody check please?
Whats the cost of a portrait and a 8x10 ??
this is not correct... sorry but hte answer is 12$:7$
Your system of equations is correct!
Let's break it down:
Let x represent the cost of an 8x10 portrait.
Let y represent the cost of a wallet-sized portrait.
For the first customer who bought two 8x10 portraits and four wallet-sized portraits and paid $52, we can write the equation:
2x + 4y = 52
For the second customer who bought three 8x10 portraits and two wallet-sized portraits and paid $50, we can write the equation:
3x + 2y = 50
So, your system of equations is indeed correct. Well done!
