The quantity of a substance can be modeled by the function K(t) that satisfies the differential equation dK/dt=-1/15K. One point on this function is K(1) = 120.
Based on this model, use a linear approximation to the graph of K at t = 1 to
estimate the quantity of the substance at t = 1.2.

Will mark brainliest if you answer ! the taco shop sold 198 lunches friday. this number is 3 more than 3 times the number they sold monday. let n represent the number of lunches sold monday. which equation shows an equality between two different ways of expressing the number of lunches sold on friday? a. n – 3 = 198 b. 3n – 3 = 198 c. 3n + 3 = 198 d. n + 3 = 198
