An iPad that was originally on sale for $1075 is now on sale for $ 623.50. What is the percent markdown( percent decrease)?

Answer = 58%

Explanation : you would have to set up a portion table were the sale amount (623.50) would go and the original/total price would go (1075$) and since you are trying to find the % you would put x over 100 , and then cross multiply while it’s set up so 623.50 times 100 =62,350 and you would take the answer and divide it by 1075x which would get you to 58 and that would equal x .

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
