There are 35 boys in the class.
Step-by-step explanation:
This question can be solved as a rule of three.
In science class, the girl to boy ratio is 3 to 7.
This means that for each 10 students, 7 of them are boys and 3 are girls.

Answer:
Step-by-step explanation:
The marginal cost function, C'(x), is the derivate of the cost function, C(x).
Therefore, we can obtain the cost function by finding the integral of the marginal cost function:
Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:
