Question

The sale of sweaters in a town changes with the temperature. If a statistical model predicts that daily sales (in dollars) are determined by the function s = 900 − 100t, where t is the temperature (in degrees Celsius), what is the temperature if sweater sales are at $1,200?

Answer 1

\(1200=900-100t\) is your equation so you have to solve for t

Answer 2

Well... you're not here
\(1200=900-100t\)
Subtract 900 from both sides
\(300=-100t\)
Divide by -100 on both sides
\(-3=t\)
