Answer:
The minimum cost per unit is obtained for an order of 8 units.
Step-by-step explanation:
Since the total cost is modeled by;
C(x)=5x²+320
Then;
1 unit costs; C(x)=5(1)²+320 = 325
cost per unit 325/1 = 325
8 units costs; C(x)=5(8)²+320 = 640
cost per unit = 640/8 = 80
80 units costs; C(x)=5(80)²+320 = 32320
Cost per unit = 32320/80 = 404
The minimum cost per unit is obtained for an order of 8 units.
Answer:
The value of x is 27
because 2 times 27 equals 54 minus 7 equals 47

Jasmine can run in one hour is 7.25 miles.
<h3>What is the formula of unitary method?</h3>
The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Given that,
Jasmine can run 4
miles in 
of an hour.
of an hour = 4 miles
= 
miles
By using unitary method we will find the value of an hour.
1 hour = 
= × 
= 
1 hour = 7.25 miles
Hence, Jasmine can run in one hour is 7.25 miles.
