Noa drove from the Dead Sea up to Jerusalem, and her altitude increased at a constant rate of $740$ meters per hour. When she arrived in Jerusalem after $1.5$ hours of driving, her altitude was $710$ meters above sea level. Let $A(t)$ denote Noa's altitude relative to sea level $A$ (measured in meters) as a function of time $t$ (measured in hours). **Write the function's formula.** $A(t)=$ [[☃ expression 1]]
