Ocean sunfishes are well-known for rapidly gaining a lot of weight on a diet based on jellyfish. The relationship between the elapsed time, $t$, in days, since an ocean sunfish is born, and its mass, $M_{\text{day}}(t)$, in milligrams, is modeled by the following function: ###$M_{\text{day}}(t)=3.5\cdot \left(1.05\right)\^{\Large t}$ **Complete the following sentence about the *weekly* rate of change in the mass of the sunfish.** *Round your answer to two decimal places.* Every ***week***, the mass of the sunfish increases by a factor of [[☃ numeric-input 1]].
