The sale price of apples at a local grocery store is $1.35 for the first kind and $1.10 for each additional pound. Which function rule shows how the cost of apples,y, depends on the number of pounds, x?

y = 1.10 ( x - 1 ) + 1.35

y = 1.10 x - 1.10 + 1.35

y = 1.10 x + 0.25

If the first pound is worth 1.35, then this number is constant, so it will be unchanged. The second and subsequent ones change, so they must contain x.
Therefore
y=1.35 + (1.10 x X)

14. The sale price of apples at a local grocery store is $1.35 for the first pound and $1.10 for each additional pound. Which function rule shows how the cost of apples, y, depends on the number of pounds, x?
y = 1.10(x – 1) + 1.35
y = 1.10x + 1.35
y = 1.35x + 1.10
y = (1.10 + 1.35)x

The correct answer is:

y = 1.35 + 1.10(x-1)

Explanation:

The cost of the first pound of apples is $1.35, which is a constant value. For each additional pound, the cost is $1.10, so we need to multiply this by the number of additional pounds, which is x-1 (since we're already accounting for the first pound at $1.35). Putting this together, we get:

y = 1.35 + 1.10(x-1)

The correct answer is:

y = -3x - 8

Explanation:

Looking at the table, we can see that as x increases by 1, y decreases by 3. This means we have a slope of -3, which is the coefficient of x in our function rule. To find the y-intercept, we can see that when x = 0, y = -8. Putting this information together, we get:

y = -3x - 8

To determine which quadratic rule represents the given data, we can plot the points on the coordinate plane and look for a parabolic shape.

Doing so, we can see that the graph has a downward opening parabolic shape. This means that we're looking for a quadratic rule with a negative leading coefficient.

From the given choices, we can see that only one equation has a negative coefficient on the squared term:

y = -x² + 5

Thus, this is our answer.
