So I’m sure most of you have experienced at least 1 time that you realized you didn’t have enough MP for the limited resulting inability to get it. Even though you could get it by Robux to save it. It is quite expensive sometimes. So to fix this, simply make so the Robux price tag for the limited car goes down the more MP you get.
How does it work? Let’s say there is a limited car at the moment and the price for it is 350 MP and 180 Robux and you only have about 310 MP on the 380 required. Now obviously, you will be tempted to buy it via Robux, now if we imply this feature. The amount required minus the cost in Robux divided by the amount of MP owned will give us a number with a decimal, turn it into a percentage and multiply the Robux price tag to the percentage. After that, simply take the number you get and subtract it to the Robux price. So it goes like this:
380 - 180 = 200
200 ÷ 310 = 0.65
0.65 → 65%
180 x 65% = 117
180 - 117 = 63 Robux
So in the end, we get an overall discount of 65% which is about 63 Robux left to pay if you want to get it via Robux and by having this amount of MP. (Yes I know this might seems dumb but trust me, it isn’t)
