Answer:
$9.38
Step-by-step explanation:
halibut is measured in pounds and a portion is measured in ounces
in order to determine the cost, the two units have to be comparable. So, ounces have to be converted to pounds
1 ounce = 0.0625 pounds
6 ounces = 0.0625 x 6 = 0.375 pounds
0.375 pounds would cost 0.375 pounds x 25 pounds = $9.38
Simplify the left side. 0.02x+(40-0.1x)=0.42x
-0.08x+40=0.42
since 0.42x contains the variable to solve for, move it to the left side of the equation by subtracting 0.42x from both sides
-0.08x+40-.0.42x=0
-0.5x=-40
x=80
