Question

the price broccoli is 1,25 per pound let y be the total cost in dollars of buying z pounds of broccoli
a x = 1.25y
b y = x + 1,25
c x = y + 1.25
d y = 1.25x

Answer 1

To express the total cost \(y\) in dollars of buying \(z\) pounds of broccoli, given that broccoli costs $1.25 per pound, we can set up the relationship as follows:

The total cost \(y\) is calculated by multiplying the price per pound ($1.25) by the number of pounds (\(z\)):

\[
y = 1.25z
\]

Looking at the options you provided, the correct equation that correlates total cost with pounds of broccoli is:

**d \( y = 1.25z \)**

However, since \(z\) isn't one of the variables presented in the options (only \(x\) and \(y\)), we can substitute \(z\) with \(x\):

If we were to let \(x = z\), then:

\[
y = 1.25x
\]

This means that if we only want to see how they relate to \(x\) instead of \(z\), you can interpret it as:

d \(y = 1.25x\)

So, **option d** is the correct answer in the context of your question.
