The absolute value would be 18 !
Answer:
let cp be x
mp= x+ (20% 0f x)= 1.2x
sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x
profit = 40
sp-cp =40
1.02x-x=40
x=2000
cp =2000
mp= 1.2*2000=2400
Step-by-step explanation:
A. Y=-0.2X+6.1.
B. It's wanting an X and Y table I guess. So week zero is 6.1. Week one is 5.9. Two is 5.7. Three is 5.5. Four is 5.3. Five is 5.1. Hope that's far enough.
The first one is 7/10 and the second one is 5/10
