Step-by-step explanation:
p(x) = 2x^2+8x-12
d(x) = x + 1
r(x) = -13
q(x) = 2x + 6
q(x)+r(x)d(x)
= 2x + 6 + (-13) * x + 1
= 2x + 6 -13 * x + 1
= 2x + 6 - 13x + 1
= (- 11x + 7)
The sales and expenditures will be $120 and it will take 12 card boxes.
Step-by-step explanation:
Cost of booth = $48
Expenditure per card box = $6
Let,
x be the number of card boxes.
Total cost as a function of x.
T(x)= 48+6x Eqn 1
Selling price of one card box = $10
Total sales as a function of x, where x is the no. of card boxes
S(x) = 10x Eqn 2
For expenditures and sales to be same
T(x) = S(x)
Dividing both sides by 4
Putting x=12 in both Equations
The sales and expenditures will be $120 and it will take 12 card boxes.
