Solve for r. 13r+1=−23r−2 drag and drop the answer into the box. r = −3 −1/3 2/3 1/8

13r+23r=-2-1
36r=-3
r=-3/36
r=-1/12

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 .
