Payback period?
If an old television cost €13.20 per month and a new one cost €32, and the new purchase costs €370, how long is the payback period? How do you calculate it, since the difference is negative.

Hello, Why do hairs repel each other after rubbing with a balloon?
Since the areas between the integration limits above the x-axis (positive sign) and below the x-axis (negative sign) are equal, the sum is 0. But why doesn’t it result in 0 here: THANKS!
I never studied physics, but I've always been interested since I was 14. I also took a quantum mechanics course and read a lot of papers. My question about whether I have particularly good common sense stems from the fact that I already had a hunch that a large amount of energy must be released…
(I know there are also universities where mathematics and physics students have the same math lectures)
Hello, I'm currently practicing for an exam and I'm having some trouble solving systems of equations when there are more than two variables and they aren't in row echelon form… Can someone help me solve the following equations step by step? I used completely different values than Geogebra. 1) 2x + 3y – z =…
Hello, can you send me a good video on how I learn to calculate expressions? I can't seem to find a good one, and does the system of equations (image) apply to both the expression and the system of equations? Could you please also send me a good video for the system of equations? Thanks…
The old TV was cheaper in operation, the new one also caused purchase costs – how to get them back in? Every month you spend more than before, you can amortize yourself. Amortizing can only be a purchase (single investment) if one saves or even achieves ongoing profits at current costs. If everything becomes more expensive, a purchase cannot amortize.
He never gets amortised!
