Question

if the temperature is 64°f, how many bottles of water should the store expect to sell?
32
80
112
144
(chart: y = 0.5x + 80, x: temperature (degrees f), y: number of bottles sold)

Explanation:

Step1: Identify the formula

The linear equation given is \( y = 0.5x + 80 \), where \( x \) is temperature (°F) and \( y \) is number of bottles sold.

Step2: Substitute \( x = 64 \)

Substitute \( x = 64 \) into the equation: \( y = 0.5(64) + 80 \)

Step3: Calculate the value

First, calculate \( 0.5 \times 64 = 32 \). Then, add 80: \( 32 + 80 = 112 \)

Answer:

112
