Question

what is the prediction of the number of coats clothes-4-you will sell when the outside temperature is 20°f? round to the nearest whole number. 1. substitute 20 for x in the equation. 2. simplify to find the value for y. at 20°f, about 86 coats will be sold at clothes-4-you.

Explanation:

Step1: Substitute \( x = 20 \) into the equation \( y=-0.86x + 103 \)

\( y=-0.86\times20 + 103 \)

Step2: Simplify the expression

First, calculate \( -0.86\times20=-17.2 \). Then, \( y=-17.2 + 103 = 85.8 \). Rounding to the nearest whole number gives \( y\approx86 \).

Answer:

86
