Help a brother out with some math? Jane bought a desk that was marked down 60% from an original price of $100. If she paid 5% sales tax, what was the total cost of the desk?

45 i think

Step-by-step explanation:

i could be totally wrong about this but im pretty sure that if an initial price is 100 percentages are really easy. so 100 minus 60 is 40 and with a 5 percent tax thats 45.

i say b hope this jdjdjdj
