Question

Katie's favorite deli has a salad bar where she can make her own salad. She has to pay $1 for the container and $3 per pound for the salad.
Write an equation that shows how the total cost, y, depends on weight of the salad in pounds, x.
Do not include dollar signs in the equation.
y=

Answer 1

To find the total cost \( y \) depending on the weight of the salad \( x \), we can break down the costs as follows:

1. There is a fixed cost of \( 1 \) dollar for the container.
2. The cost for the salad is \( 3 \) dollars per pound, which can be calculated as \( 3x \) where \( x \) is the weight in pounds.

Thus, the total cost \( y \) can be expressed as:
\[
y = 1 + 3x
\]
