Question

Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of colour brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of colour brochures. Which system represents this situation?

Answer 1

Explanation:

Let's represent this situation with a system of linear equations. Let \( x \) be the cost of a black-and-white brochure box, and \( y \) be the cost of a colour brochure box.

The initial order can be expressed as:

[ 4x + 3y = 134]

After running out and ordering more, the second purchase is represented by:

[ 3x + 3y = 120 ]

This system represents Christian's brochure purchases.

hopefully this helped u out! :)
