Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3
+ 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3
+ 7x - 40 = 60
⇒ 0.3
+ 7x - 100 = 0
⇒ 3
+ 70x - 1000 = 0
⇒ x = -70 ±
× 
⇒ x = -70 ± 130 × 
⇒ x = 10 or -
Quantity sold cannot be negative giving us the value of x as 10 units.
Answer:
38/3
Step-by-step explanation:
s is the midpoint of RT
so, RS = ST
5x + 7 = 8x -31
7+31 = 8x-5x
38= 3x
x= 38/3
