A researcher monitoring the power from the solar panels on a Mars landing has developed a linear model for the available power output in watts, P, against the number of days since landing, d, to help predict the change in power due to dust accumulation. The equation is P=215.4−0.422d
Based on the model, by how many watts will the power chage over 10 days?(1 point)
