Question

Write an equation to represent the following situation: Matt spent $10 on supplies to make necklaces. He sells each necklace for $2.00. How much, y, is his profit.

Answer 1

This equation represents the situation where Matt spent $10 on supplies to make necklaces and sells each necklace for $2.00, and it calculates his profit as a function of the number of necklaces he makes and sells.

Explanation:

Let x be the number of necklaces that Matt makes and sells.

The total revenue that he earns from selling these necklaces is 2x dollars, since he sells each necklace for $2.

The cost of making the necklaces is a fixed amount of $10, regardless of how many necklaces he makes.

Therefore, his profit, y, can be calculated by subtracting the cost from the revenue:

y = 2x - 10

This equation represents the situation where Matt spent $10 on supplies to make necklaces and sells each necklace for $2.00, and it calculates his profit as a function of the number of necklaces he makes and sells.
