Answer:
4(q - 10) = 76.
q = 28.
Step-by-step explanation:
Let the number of questions be q.
The number Tim got right is therefore q - 10 questions.
4(q - 10) = 76
4q - 40 = 76
4q = 116
q = 116/4
q = 28.
Answer:
C(p) = p*50 + 300
Step-by-step explanation:
Using the names:
Clm: cost of labor and materials
Crm: fixed cost on rent and equipment
p: number of phones
and Ct: total cost
the ecuation would be number of phones times the cost and material plus the fixed cost, something like this
p * Clm + Crm = Ct
on the example we have all the data except the rent and equipment cost (the fixed cost) so thats what we need to solve
producing 3 phones its
3 *¨50 + Crm = 450
Crm = 450 - 150 = 300
so replacing in the above formula the equation would be
C(p)=p * 50 + 300
