Hi!
We will solve this using rations, like this:
$920 equals to 115% = 1,15
$x equals to 100% = 1
_______________________
x = (920*1)/1,15
x = 920/1,15
x = 800
Store earned 15%, or in this case 920 - 800 = $120.
Hope this helps!
Answer:
maybe its so we can easily find the relationships between the numbers
Step-by-step explanation:
Answer:
x = 3
ST = 24
Step-by-step explanation:
if T is the midpoint then ST = TU
8x = 2x + 18 move like terms to the same side
8x - 2x = 18 subtract like terms
6x = 18 divide both sides by 6
x = 3 to find ST replace x with 3
