You can just plug the coordinates in.
Answer:
320
Step-by-step explanation:
(45*3.5)+(65*2.5)=320
Answer:
-6
Step-by-step explanation:
You have to multiple -2 by 15 and -8 separately
8 - 2(15-8)
8 -30 + 16
24-30 = -6
.11x+.08(180000-x)=17400
.11x+14400-.08x=17400
.03x=3000
x=$100,000 at 11%
$80,000 at 8%
