SAT Linear functions Question

$$m(t)=-0.0274{\left(\frac{t}{7}\right)}^2+7.3873\left(\frac{t}{7}\right)+75.032$$ The function $m$ gives the predicted body mass $m(t)$, in kilograms (kg), of a male giraffe $t$ days after it was born in a wildlife reserve, where $t\le 390$. Which of the following is the best interpretation of the statement “$m(370)$ is approximately equal to 389” in this context?
