Answer: 10% decrease
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the difference between the prices:
Decrease: original cost - new cost
100,000-90,000= 10,000
Then we have to divide the decrease by the original number and multiply it by 100 to obtain the percent decrease
(10,000/100,000) x 100 =0.1 x100=10%
