Answer:
$1080
Step-by-step explanation:
Take 1800 and put it over 5, like a fraction and solve to make the denominator 1. Then multiply by three because we are looking for the cost of 3 machines
x = 1
(x^2-4x+3=0 or sin(x)=1)
( x^2-4x+3=0 or sin(x)=1)
31
1/4 of 124, ¨of¨¨ represents multiplication
so 1/4*124=124/4
which 124 divided by 4 equals 31
9/2
x < –4 or x ≥ 3
