Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain
GarryVolchara [31]
Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10


423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!
