Zoe is making greeting cards, which she will sell by the box at an arts fair. She paid $48 for a booth at the fair, and the mate

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)

$48+6x=10x\\48=10x-6x\\48=4x\\4x=48$

Dividing both sides by 4

$\frac{4x}{4}=\frac{48}{4}\\x=12$

Putting x=12 in both Equations

$T(12)=48+6(12)\\T(12)=48+72\\T(12)=\$120$

$S(12)=10(12)\\S(12)=\$120$

The sales and expenditures will be $120 and it will take 12 card boxes.
