Answer:
49 and 121 are perfect squares.
Step-by-step explanation:
By definition, a perfect square is a number that is generated by multiplying two equal integers by each other.
7 ×7 or 7² = 49
11 × 11 or 11² = 121
Another way of checking whether a given number is a perfect square:
Finding the number’s <em>square root.</em> If the square root of a number is a whole number, then the number is a perfect square.


Therefore, 49 and 121 are both perfect squares.
C - fixed costs; b - costs per bicycle;
c + 110 b = 10,900
c + 130 b = 11,600
c = 10,900 - 110 b
10,900 - 110 b + 130 b = 11,600
20 b = 700
b = 700 : 20 = $35
c + 110 * 35 = 10,900
c + 3,850 = 10,900
c = 10,900 - 3,850
c = $7,050 ( daily fixed costs )
Marginal cost is the cost of producing one more unit of goods ( one more bicycle ).
Answer:
The company`s daily fixed cost is $7,050.
The marginal cost per bicycle is $35.
