Question

Pineapples are on sale for $1.50 per pound. Let y be the total cost in dollars of x pounds of pineapple. Which equation represents the situation?

A. X = y + 1.5
B. Y = x + 1.5
C. Y = 1.5x
D. X = 1.5y

Answer 1

The equation that represents the situation is C) Y = 1.5x, which shows that the total cost is equal to the price per pound multiplied by the number of pounds.

Step-by-step explanation:

The equation that represents the situation is Y = 1.5x.

This equation shows that the total cost, represented by Y, is equal to the price per pound, which is $1.50, multiplied by the number of pounds, represented by x.

For example, if you want to find the total cost of buying 3 pounds of pineapple, you would substitute 3 for x in the equation:
Y = 1.5 × 3 = 4.50 dollars.
